Weekly Pac-5: Offensive Rebounders

Posted by Adam Butler on February 10th, 2017

In last week’s Pac-5 we discussed the most frustrating of turnovers in an exploration of the teams that cause their coaches and fans the greatest angst. This week we’ll continue that line of inquiry, but instead of considering the victims, we’ll highlight the culprits. The unforced turnover is without a doubt the game’s most frustrating play, but an offensive rebound comes in a close second. Defending your way to a missed field goal simply to have to do it all over again is incredibly disappointing. The offensive rebound is brutal.

Unless, of course, you’re on the side of the offense! In that case, you’ve refreshed your thirty or put yourself in excellent position for a putback (read: easy bucket).

The Pac-12’s top offensive rebounders as determined by offensive rebounding percentage:

  1. Ivan Rabb, California – 13.4% – Rabb, who was recently omitted from the late-season Wooden Award list, is a fitting first place offensive rebounder. Remember last week when we noted that the Golden Bears were coughing the ball up at wild levels? Rabb’s acquisition of extra possessions is a huge reason why they can endure that frustrating practice.
  2. Thomas Welsh, UCLA – 13.4% – Consider that UCLA leads the nation in eFG% and thus isn’t missing many shots; then consider that it’s borderline unfair that the Bruins have a guy gobbling up extra shots on what few attempts they miss.
  3. Michael Humphrey, Stanford – 11.9% – One thing that I’ve long wondered was whether Jerod Haase would follow in the footsteps of his mentor, Roy Williams. In the instance of offensive rebounds, it’s worth noting that North Carolina has been a top-25 offensive rebounding team for 13 of the last 14 seasons. So while Stanford might not resemble the Tar Heels in many meaningful ways, Humphrey is at least trying to fit the mold.
  4. Kingsley Okoroh, California – 11.8% – With Rabb already listed here, its worth noting that the Bears are collectively the 55th-best offensive rebounding team in college basketball (by rebounding rate).
  5. Dusan Ristic, Arizona – 11.2% – As teams continue to play zone against Arizona, there should be many more opportunities for Wildcats like Ristic to grab misses. Note that Ristic’s teammate, Rawle Alkins, rates as the top offensive rebounding guard in the conference.

Weekly Pac-5: Unforced Errors

Posted by Adam Butler on February 3rd, 2017

The unforced error, most commonly quantified in tennis, is universally agreed upon as annoying. No matter your task, an error sustained but perhaps not earned, is peak frustration. As it translates to basketball, the non-steal turnover would seem to be among the most frustrating of unforced errors. This is the time of ball forfeiture that looks like an errant pass, a dribble off the foot, or an extra step and a travel. I imagine you cringed just reading that list.

Cal Outlasted Utah Last Night Partially Because of a Low 10 Turnovers (USA Today Images0

In this week’s Pac-5, we look at the Pac-12’s leaders in unforced errors. To quantify this, we’ll look at the percentage of a team’s turnovers that were not caused by theft. Here are the Pac-12’s team leaders in unforced errors:

  1. California, 64% of turnovers are non-steals – This is in fact a nationally bad number, ranking as the ninth-highest such ratio in college basketball. It might be particularly frustrating when you consider there are three seniors in Cal’s backcourt. There is, of course, also a freshman, Charlie Moore, who actually leads the Golden Bears in turnover rate. Furthermore, by volume, this must be wildly frustrating as the Bears play at the slowest tempo in the conference. That’s a lot of UFEs.
  2. Arizona, 60% – This one doesn’t hurt too bad when you consider the Wildcats commit a percentage of turnovers that is about at the national average.
  3. Washington, 58% – Considering that all these coughed-up opportunities could actually be Markelle Fultz jumpers? Also, Fultz owns the nation’s 28th-highest usage rate yet turns the ball over on just 14.9 percent of possessions.
  4. Oregon, 56% – Last season, Casey Benson had an outrageous handle at the point. This year he’s yielded those minutes to a Payton Pritchard, a freshman, who’s perhaps a greater scoring threat but something more of a turnover liability (as is Dillon Brooks, at 21%).
  5. Utah, 55% – We’re inching towards the national average (54%) so maybe this one isn’t as tough a pill to swallow as, for example, Cal? Too soon to mention those two teams in the same sentence?

NOT LISTED: Oregon State. The Beavers have the sixth highest turnover rate in the nation, which by itself is frustrating. They’re turning the ball over (stolen or otherwise) on nearly a quarter of their possessions.

Weekly Pac-5: Zone Defenses

Posted by Adam Butler on January 27th, 2017

While the “beautiful game” is generally reserved for soccer (futbol), there is indubitably some innate beauty to this game of basketball. This season, UCLA has received a lot of hype surrounding its beautiful style. Its tempo, shot-making, passing, and creativity has captivated the nation. As recently as a week ago, they were the #3 team in college basketball, boasting the second most efficient offense of the KenPom era (2002). And now the Bruins have sustained two consecutive losses, most closely attributable to their defense. In one of those defeats, their offense remained spectacular. Arizona made a strategic decision to put some of its lock-down defenders on the Bruins’ peripheral players. They would let Lonzo Ball outscore them. He tried, valiantly, but couldn’t. USC, however, turned UCLA’s beautiful offense ugly. The Trojans’ zone defense forced the worst offensive performance (by efficiency measures) of UCLA’s season. USC has now won four straight over the Bruins.

As far as beautiful offense goes (consider a pure jumper splashing through the net in contrast with a great defensive stance), this will always be a two-way game. In considering aesthetics as well as USC’s disruption of UCLA’s beauty on Wednesday night, let’s explore how the Pac-12’s five most zone-enthusiastic defenses fare in executing this strategy (all data is acquired from Synergy Sports and enthusiasm is measured by total number of possessions played in zone).

For UCLA, It’s Defend or Die…

Posted by RJ Abeytia on January 25th, 2017

The second game of six between the three best teams in the Pac-12 was an undeniably entertaining epic that left Arizona reinvigorated as a Final Four contender and UCLA with a clear ultimatum: Defend or die. It’s not like the Bruins had convinced anyone that they were a solid defensive team to this point in the season — UCLA entered the game hovering around the middle of the Pac-12 in defensive efficiency. The Bruins’ marquee win in Lexington over Kentucky came on the strength of their offense (1.17 PPP) and their only other loss came to an Oregon team they ultimately couldn’t defend (1.24 PPP). The national spotlight tends to expose and crystallize the flaws of even the elite teams in college basketball, and Arizona on Saturday in Pauley Pavilion exposed UCLA’s middling defense as an Achilles’ Heel that may very well short-circuit a deep NCAA Tournament run.

The Bruins’ major issue against the Wildcats was defending the paint via the drive. Kobi Simmons, Kadeem Allen and the newly-eligible Allonzo Trier pounded the paint relentlessly, often singularly focused on their easy target, UCLA guard Bryce Alford. Alford is having an exceptional season playing off the ball next to All-Universe Point Guard Lonzo Ball, but the senior was no match for the physicality and athleticism of Allen, who relentlessly attacked the basket when isolated against him. Arizona’s 34 points in the paint was also a result of mediocre post defense. Dusan Ristic contributed 11 points; Chance Comanche 10; and Lauri Markannen, he of the skyrocketing draft stock, repeatedly took TJ Leaf well outside his defensive comfort zone in nailing 3-of-4 from behind the three-point line as well as grabbing the offensive board and ensuing dunk that effectively ended the contest.

Should We Care About Who Shares? Offensive Efficiency vs. Assist Rate

Posted by RJ Abeytia on January 21st, 2017

If you grew up in the ’80s and you loved the game of basketball, Magic Johnson and Larry Bird changed the way you watched it, judged it and maybe even played it. One of the cornerstones of their impact was the elevation of the assist both as a highlight play and as a marker of a player’s impact. In today’s game, there is no better criteria for evaluation than efficiency. Assists make basketball the beautiful game, providing gasps in appreciation and awe at the sport played in its most fluid and selfless form. However, when it comes to college basketball — a game which has undergone a tectonic shift or 10 since the days of Bird and Magic — the question becomes, how valuable is the assist?

Lonzo Ball is one of many high assist/high efficiency standouts in the conference this season. (Getty)

To answer that question, the first place to start is by cross-checking team offensive efficiency with assist rate. Here is how the Pac-12 looks.

Offensive Efficiency Assist Rate
1. Oregon Oregon
2. UCLA Arizona
3. Arizona UCLA
4. Arizona State Washington State
5. Utah Stanford
6. Colorado Oregon State
7. California USC
8. Washington Colorado
9. Washington State Utah
10. Stanford Arizona State
11. USC California
12. Oregon State Washington

The eyeball test clearly shows a strong correlation between Pac-12 teams in terms of their assist rates and efficient offenses. There’s no room at the top without great ball movement, but the line between offensive success and assists gets somewhat obfuscated at the bottom. Stanford, Oregon State and USC all rank among the top half (okay, USC is seventh) in assist rate, yet each team still struggles offensively. Conversely, Arizona State has a proficient offense this season without the services of a great assist rate. If assist rate turns out to be an important metric, we would expect the Sun Devils to regress offensively while the Cardinal, Trojans and Beavers should ascend. If we simply resign ourselves to this unscientific snapshot, it’s fair to say there’s a light correlation between offensive efficiency and assist rate, but the two metrics are not collinear.

Allonzo Trier’s Suspension: More Questions Than Answers

Posted by Mike Lemaire on January 19th, 2017

Just minutes before Utah was set to play Washington State in what promised to be one of the least exciting Pac-12 games of the week, ESPN made things much more interesting by reporting on the reason behind Arizona star Allonzo Trier’s long suspension. A poorly kept secret for months in college basketball circles, Trier’s indefinite suspension was the result of a positive test in September 2016 for a performance-enhancing drug. According to the report, Trier had appealed the suspension and won, but the NCAA would not allow him to play until the drug had completely exited his system. This explains why no one has been able to provide realistic timetables on when the sophomore guard would be back on the court.

Allonzo Trier Has Been a Mystery Man at Arizona This Season (USA Today Images)

This is a compelling story for a myriad of reasons. First, any time one of the most recognizable programs in college basketball is involved in something newsworthy, it is going to draw interest. Second, there just aren’t many historical instances where a college basketball player has been suspended for PED use. A quick Google search turns up a number of stories on college football players getting suspended for PED use, but there are very few high-profile cases of PED use in college basketball. Finally, what makes this story so fascinating is the way it has been handled from the very beginning.

Pac-12 Weekly Power Rankings: Vol. 3

Posted by Pac-12 Team on January 18th, 2017

The Pac-12 last season boasted the toughest road game in college basketball. During conference play, the league’s home teams won at a higher rate (71%) than any other conference in America. This season, Pac-12 home teams are winning at just a 59 percent rate. They say that conference titles are won on the road. How has your team fared in hostile territory?

Plenty to smile about for Dillon Brooks and Oregon lately. (Cole Elsasser/Emerald)

  1. Oregon (1) – The Ducks’ conference dominance continues. Since their dramatic, two-point victory over UCLA in the Pac-12 opener, Oregon has simply decimated their opponents. Oregon’s average margin of victory over the last four games is 26.5 points, a full 15 points higher than UCLA. Granted, the four teams the Ducks have played also have a combined 6-15 conference record, but at least they are taking care of business.
  2. UCLA (2) – How do we convince Thomas Welsh to get to the free throw line more often? That is the question that head coach Steve Alford should be asking himself. After shooting 75 percent from the charity stripe last season, the junior has yet to miss in his 24 attempts this year (leading to a subtle breakout season for the junior). Now if he could just average more than one freebie attempt every two games… Read the rest of this entry »

Can Michael Porter Jr. Save Lorenzo Romar’s Job at Washington?

Posted by Mike Lemaire on January 18th, 2017

On Monday in a gym in western Massachusetts nearly 3,000 miles east of Seattle, Nathan Hale High School (WA) forward Michael Porter, Jr. lit up an Oak Hill Academy team littered with Division I talent to the tune of 37 points, five rebounds and four assists. Back in the Emerald City, Washington head coach Lorenzo Romar is in danger of losing his job. The Huskies are drowning in a sea of defensive lapses and wasted offensive possessions, all the while squandering the services of arguably the best player in college basketball, Markelle Fultz. Over the last 15 years, Romar has banked significant good will as the most successful head coach in program history. But as the Huskies have churned out legitimate NBA talent over the past five seasons without any real NCAA Tournament success to show for it, even his staunchest defenders have begun to come around. And yet, the only person that seems to stand between Romar and a near-certain axing is the 18 year-old Porter.

Michael Porter Jr. is really good, but is he good enough to keep Lorenzo Romar from being fired?

The prep superstar is a lot of things. He is the No. 2 overall recruit in the Class of 2017 and a likely NBA lottery pick in 2018. He is also Romar’s godson and the crown jewel of Washington’s next recruiting class. His father, Michael Porter, Sr., is currently an assistant coach there, and his younger brother, Jontay Porter, is a top 40 recruit in the Class of 2018 who may reclassify to join his sibling in Seattle as soon as next season. Fans and administrators alike are well aware of the significant athletic gifts of the Porter brothers, but they are also well aware that the Porter brothers are only committed to Washington for as long as Romar and their father remain employed by the university.

Arizona’s Offense Has Saved Its Season

Posted by Mike Lemaire on January 13th, 2017

When Parker Jackson-Cartwright sprained his ankle in a game against Texas Southern on November 30, Arizona head coach Sean Miller must have been worried. His team’s offense, already a concern because of the retirement of Ray Smith and the continued absence of Allonzo Trier, was about to lose its only true point guard. To that point, Jackson-Cartwright had amassed a healthy 37 assists to just 11 turnovers and it stood to reason that, with the Wildcats’ best playmaker hurt and the schedule only getting tougher, an inexperienced offense would struggle to score. Instead, Arizona lost just once in the six games Jackson-Cartwright missed (to unbeaten Gonzaga) and have yet to suffer a defeat since his return. A team that ranks 325th nationally in experience is now quietly 15-2 overall and keeping pace with Oregon and UCLA at the top of the Pac-12. Miller’s defense, of course, deserves a lot of credit. His pack line scheme is one of the stingiest in the country, but that’s true most every year — the man can teach defense. Rather, that Arizona’s offense ranks among the best 30 in the country is the story in Tucson.

Arizona’s rotation effectively has one above-average three-point shooter and one above-average passer. It ranks 278th in adjusted tempo and 330th in its share of three-pointers taken within the offense. Yet the Wildcats average roughly 1.14 points per possession to this point (1.11 PPP in conference play), and if Trier can return at nearly 100 percent, they look like the third horse in what appeared to be a two-way battle for conference supremacy. It should be noted that Arizona’s offense has been more mediocre against top 100 opponents, but there are three key reasons why the team has been able to stay afloat offensively.

Pac-12 Weekly Power Rankings: Vol. 2

Posted by Pac-12 Team on January 11th, 2017

Ivan Rabb thwarted away last weekend’s final shot, cementing his Player of the Week title and lending us little clarity on the Pac’s mid-section. The second volume of our Pac-12 Power Rankings saw minimal movement as home favorites mostly held court, road warriors fought and Oregon State got rolled (-22.9 conference efficiency margin). Last week’s ranking in parenthesis.

The Ducks Are Coming (USA Today Images)

1. Oregon (1) – After toppling the two southern California undefeated teams last week, Oregon continued its conference domination again in beating the Washington schools by a total of 41 points. What’s most impressive is that the Ducks did this with star Dillon Brooks playing only 25 combined minutes. Oregon’s depth was on full display as Tyler Dorsey picked up the slack against Washington (a career-high 28 points, including eight threes) and Chris Boucher did the same against Washington State (a career-high 29 points, including six threes).

2. UCLA (2) – Depth has become a minor concern for UCLA as Steve Alford has stuck to a very tight rotation. UCLA ranks just 343rd nationally in bench minutes and it is clear that Alford does not yet trust big men Ike Anigbogu or Gyorgy Goloman. It has not been an issue to this point, of course, but it will be something to keep an eye on as conference play progresses.

3. Arizona (3) – The Wildcats still can’t leap over the Ducks and Bruins despite a 4-0 conference start, but two storylines are emerging in Tucson that could very well vault Arizona to the top of the rankings. First, the Wildcats continue to defend very well, surrendering fewer than 70 points in 16 of its last 17 games (Colorado) and producing a conference-leading Defensive Rating of 88.3. Secondly, the Dusan Ristic Experience is real. In Pac-12 play, Ristic carries an effective field goal rate of 64.4% and an Offensive Rating of 126.7. He has provided good post play on both ends, taking some of the pressure from Lauri Markannen while also at times stepping into the spotlight himself. Sean Miller‘s team appears to be rounding into a team with deep March prospects.
