Trace McSorley has faced plenty of doubt as a quarterback throughout his career. Outside of Penn State, not many colleges recruited him to play that position.

At the NFL Combine, McSorley is facing some more doubt in his ability to play quarterback at the professional level, despite rewriting Penn State’s record book. According to the NFL Draft’s official Twitter account, McSorley was one of a handful of players asked to work out at a second position.

NFL teams are requesting to see McSorley with the defensive backs.

It’s not unusual to see some players work out with a second position at the combine. And, usually, it’s a benefit to show off your versatility in front of NFL scouts. But defensive back is quite a bit different than quarterback.

McSorley could use it as motivation to prove himself at quarterback.

Throughout his Penn State career, McSorley shouldered a lot of offensive weight. He was a proven winner capable of making big-time plays, both with his arm and his legs. But clearly there’s still some doubt in the minds of at least a few NFL teams about whether he can perform at the next level.

McSorley could change their minds at the combine.
