How many drives a game does each team generally get? Well, if you use all of the FBS then the average is about 12.8. Below are charts that plot the difference from the mean for each team. A negative number means that team gets fewer drives per game than the average.
The Big 12 as a league averages higher than this (maybe not a surprise given the HUNH, but that means more plays not necessarily more drives).
TCU actually has more drives than any other team in FBS at almost 15 a game. Not surprising, KSU has the least in the Big 12 at just under 12.
