He had major shoulder surgery. Shoulders are never the same after surgery. IIRC he had a torn labrum. The worse kind of shoulder injury. He's been playing AB for 2 years now. Depending on Leggett's head injury...it's the Laskey/Connors show this year at BB.
He can't handle carries up the middle because of his shoulders but he can block LBs, DEs, and DBs? OK...
After Laskey you have:
Conners: former walk on, 2nd string but CPJ feels the need to rep Synjyn at BB "just in case"
Wilson: Redshirt freshmen who spent last season as an AB. Wouldn't even be in the discussion at BB had Brendan Douglas signed and Custis was still here.
CJ Leggett: True freshmen. Enough said.
If CPJ was confident in the backups you seriously think Days would be repping at BB? Perkins is a starting AB on paper right now, but that doesn't mean CPJ would never move a player because of need (see: Donovan Wilson). Let's not forget, Perkins was the starting BB at one point.
