Prior has a shot at being there at 21. Depends on how the board falls and who else is there, and whether TT likes him.
I'd think 5'11" safeties that run a 4.6 can be found outside of R1. Seems TT likes safeties that are either bigger (burnett, richardson, rouse) or better athletes (collins), so I'm skeptical about Prior's chances of being on GB's roster.
Which means I'll be wrong.

If Allen Robinson is there in R3 and TT hasn't picked a WR yet, I'd like that pick.
