Referees have called an average of 42.29 personal fouls per game this season through Sunday night, about seven more per game than last season. About 19.5 percent of games have featured 50 or more personal fouls and seven have produced 60 or more, numbers that suggest the new rules have been enforced with particular zeal a handful of times by certain crews.

The purpose of the new rules was to curb college basketball's downturn in scoring by weaning defenders off hand-checking or arm-barring and forcing them to play defense with their feet. The proliferation of rough, bruising defense is likely one of the culprits for scoring in Division I plunging to 67.5 points per team in a game last season, the lowest in 31 years or the entirety of the 3-point era.
