• The four dirtiest teams in this sample were the University of Texas San Antonio, UMass, Idaho, and South Alabama, all of whom made the jump from lower-level football to the FBS at some point in the last decade. This result might make sense to anyone who’s found themselves physically outclassed in competition — sometimes your only recourse is to hack, shove, and elbow and hope the ref doesn’t see it — except that UTSA was actually not bad last year, its first at the FBS level, putting up an 8-4 record. UTSA’s coach, by the way? Larry Coker, late of the University of Miami.



• The most misbehaving team of the last decade in a single season: last year’s UCLA squad, which racked up a remarkable 45 personal fouls and eight unsportsmanlike conducts over the course of 14 games.

I watched South Al in person last year. Didn't strike me as playing dirty but they had a couple offensive linemen who consistently failed to make from the huddle to the line of scrimmage without being able to remember the snap count.

I would like to see the fouls per play instead of per game. Wisconsin and the service academies have many fewer plays per game than teams that run up tempo spread.

Despite the lack of personal fouls, Air Force has a "dirty" reputation within the MWC, due to an emphasis on cut blocking in their scheme.
