I thought I read something that said prime only has 20 scholarship players on the roster.
Maybe 20 from last year's team. Probably fewer by the time this post goes through. But there are more transfers than that, plus incoming frosh of course. So far only 3 players have transferred to another P5 program and one of those was a kicker. Roddick is the only legit player I'd like to have back, plus maybe Sami just for a warm body on the interior DL. Supposedly we have some transfer commits who are set to announce soon but many fans are freaking out about the number of bodies needed to be replaced. The thing is, most of the players being replaced aren't even G5 starter quality so even making lateral replacements shouldn't be too tough. DT is the biggest area of concern as you need depth and there aren't a ton of quality players available, unlike the skill positions.
Edit: just checked 247 and we currently have 31 incoming transfers plus 17 incoming freshmen, probably about half of whom are currently on campus.
