Is Iowa State’s Defensive Improvement Sustainable?
Posted by Chris Stone on December 11th, 2015Last week I wrote about Oklahoma’s defensive transformation powering its rise up the college basketball rankings. This week, we may be seeing something similar happening in Ames, as Iowa State now ranks 21st in adjusted defensive efficiency after the Cyclones ranked 71st in the statistic a season ago. While the team has clearly improved on the defensive end under new head coach Steve Prohm, its performance in last night’s 83-82 win over Iowa begged the question on whether the defense has really turned the corner. The Cyclones this season continue to limit free throw attempts and shots at the rim (and did so again versus Iowa on Thursday), so what’s made them better?
Coming into the year, Prohm’s stated goal was to improve the defense in three key areas: transition, defensive rebounding, and three-point defense. “It starts with transition defense,” Prohm told the Ames Tribune back in October. Taking away easy baskets is a great way to make your defense better, and the Cyclones have had a bit more success in that area this season. While opponents are still attempting nearly the same percentage of their shots in transition, they are shooting about five percent worse on those attempts, according to hoop-math.com. The Cyclones have also found success keeping opponents’ off the offensive glass. Iowa State ranks 22nd nationally in defensive rebounding percentage, up from 106th last season. Opponents are snagging about six percent fewer misses this season. While Prohm has emphasized the role his guards can play in defensive rebounding, it’s actually been Jameel McKay (19.2 percent to 22.3 percent) and Georges Niang (15.2 to 17.1) who have seen their defensive rebounding percentages rise. Finally, Prohm wants his team to play an aggressive defensive style that includes running teams off the three-point line, but so far the ‘Clones have failed to do that. Teams are attempting 37.8 percent of their shots from behind the arc against Iowa State, up from 34.3 percent last season. That hasn’t come back to hurt them, though, because opponents are shooting just 29.3 percent from deep against Iowa State in 2015-16.
