Five Years Later: Has Longer Three-Point Line Achieved Desired Results?

Posted by BHayes on October 3rd, 2013

With five full seasons of college basketball’s 20-foot, 9-inch three-point line under our belt (formerly 19’9″), now would seem like a good time to take inventory on the impact of the rule change. There was ample debate back in summer 2008 on just how much of a difference the extra foot would make, but believers, and more importantly, the enforcers (the NCAA) trusted that the new line would promote better offensive spacing, and again make the three-pointer an option for only the finest of shooters. Those on the other side of the debate refused to believe that a measly 12 inches would alter a whole lot, with common refrains ranging from “players will be able to adjust very quickly” to “most three-point attempts came from well beyond the arc anyways.” So which group gets to say “I told you so” now? We have a large enough sample size to draw legitimate conclusions, but if we recall the initial objectives of the rule change – increased floor spacing and a decrease in non-shooters attempting the shot —  it’s  hard to argue that the evidence shows anything but mixed results.

At the simplest level, the new line served its purpose: Three-point shots have been harder to make since 2008-09. In the last decade, the peak of three-point shooting proficiency came in the final year of the 19’9” line, when players shot 35.02% from distance. That number immediately plummeted to 34.18% in the first year with the new line — a significant drop when you consider that the largest shift in percentage in the five years prior was just .21%. Also worth noting is that the overall percentage in each of the last five years is well below even the lowest percentage (34.49%) in the five years before the change. StatSheet has some wonderful visual representations of this data, and it doesn’t take a genius to figure out that college players are simply not making as many threes as they did when the line was shorter. No PhD necessary to deduce that they are also taking fewer threes – another desired outcome for the rule book authors back in 2008. Total attempts saw a drastic decline between 2007 and 2008, as the average of 38.25 3FGAs per game fell to just 36.73 in the year after the change. That number has experienced a relative flatline in the four years since – a sharp interruption to a decidedly upward trending graph in the years prior.

A whole generation of kids will now have their foot on the line…

Posted by rtmsf on May 3rd, 2007

If you didn’t already catch it, the NCAA was busy again today.  After taking away our text messages and putting the whomp down on academic rogues in the last week, it decided that beginning in the 2008-09 season, college basketball will move back its three-point line by a foot to 20 feet, 9 inches.  This remains three feet shy of the NBA range at the top of the key, but inexplicably, it is three inches longer than the international distance.  In keeping with NCAA decisionmaking, this extra three inches makes almost no sense, considering that a given court could have as many as four different three-point lines on it – women’s NCAA (staying at 19’9), international (20’6), men’s NCAA (20’9) and NBA (23’9).

Three pointer

Notwithstanding the playing surface chaos we anticipate at the likes of UC-Santa Barbara and other schools that use their home floors for volleyball in addition to men’s and women’s basketball (so… many… lines…), some coaches have chafed at the change because it did not also address the width of the lane.  Their complaint is that if you are trying to open up the court and reduce physical play by extending the three-point distance, you need to also expand the width of the lane to compensate for the post men’s strength inside.  In our worldview, though, anything that provides for less bumping and grinding in the paint is without question a good thing.  See: Suns, Phoenix, for a template on this style.     

Although we question the confounding extra three inches, we actually believe this is a good rule change for player development purposes as well – and overdue, at that.  When the 12 year olds at your local rec center (or this kid!) can consistently hit the current three-point shot, it’s probably a little too easy for college athletes.  Plus, every additional inch will provide a disincentive for guys who shouldn’t have been shooting threes in the first place – do you hear us Jacque Vaughn/Wayne Turner/TJ Ford?
