There are many reasons why FBS teams are allotted 85 scholarships despite never having more than 11 players on the field at any given time. JB Brown is one of those reasons.
Brown was expected to play more this season than as a true freshman in 2017, when he appeared in four games as a third-string defensive end, someone who could provide depth at a critical position for the Arizona Wildcats.
Then junior Justin Belknap suffered a broken foot before Arizona’s third game this season, requiring surgery and ending his season, and Brown suddenly went from backup to starter.
