Shakir Bell is legit. Seen him play several times. Going to be a steal and I think he can be more of an every down back than his size (5-9, 185) would indicate. The name Darren Sproles keeps coming up with him. His teammate Ben Obaseki is probably a UDFA, but I think he can make an NFL roster.
Mark Jackson from Glenville St. is a mauler at OT. Looks like a RT or RG though. Big boy.
I also like the small school safeties, such as: Rontez Miles (CAL PA), Malcolm Bronson (McNeese), Kejuan Riley (Alabama St).
