(After the Daniel Awoleke near miss, we double and triple checked this one -- there is no #91 on the 2016 roster.)
#91 DT Keith McCaskill
2007-2011, 6'0", 284 lbs.
Career Stats: McCaskill played in 50 games for the Bulls and started 16, mostly in his 2011 senior season. He finished his USF career with 72 tackles, 17 TFL, 7.5 sacks. two quarterback hurries, and six pass breakups. He also forced a fumble against Syracuse in 2008. His best season was 2011, when he picked up eight TFL and four sacks.
How He Came To USF: McCaskill played at Tallahassee's Godby High School with his twin brother Kevin (who also played for the Bulls as a center). Keith played defensive end and linebacker at Godby, and started getting noticed by college scouts after his junior year, when he racked up 95 tackles, eight sacks, three forced fumbles, and two recoveries. He chose USF over an offer from Illinois, which makes sense because Ron Zook was coaching them at the time.
Recruiting Rankings: All the major scouting services rated Keith as a two-star prospect. Curiously, Rivals and 247 categorized him as a tight end prospect.
His Best Game: Against Miami in 2011, McCaskill had four tackles and sacked Jacory Harris twice. His first sack came late in the third quarter with the Hurricanes threatening to score. It killed Miami's drive, and led to a missed field goal that Ryne Giddins got a hand on. The second sack could have stopped Miami's final drive, but they wiggled out of a 2nd and 16 to keep it going.
But that's not his most famous game or moment. That was against Rutgers in 2010. Keith McCaskill has attained USF legend status for being on the business end of the Rutgers screen pass out of their own end zone safety. This play will outlive us all.
