Swervin, I agree to be honest. I know Boyd has slipped on many draft boards, and he had a lot of drops this year and of course the HUGE drop in last year's bowl hurt as well. But he does so many other things so well.
I think he leaves and get picked in the third round unless he does amazing in the combine. Really... as you say, the draft grades mean absolutely nothing, and honestly how you play means like 25%... the combine is what matters. If Boyd preps and runs a 4.28 and benches 8 minivans then he gets into the first round. If he runs a 4.7 and pisses mj then he will be drafted in the 6th round. He is one of those guys that matter that much.
Aaron Donald have off the chart numbers at the combine, and I remember seeing mock drafts, after he won EVERY AWARD possible having him go 28-40th in the draft before the combine, and after his combine performance they had him between 7-15th. The reason he didnt go even higher was his actual size was small for an NFL DT.
Boyd has the same issues. He isnt 6'5, 220 Dez Bryant looking or even Fitzgerald looking. As a real player, he will kick arse in the NFL just like most Pitt guys. He is far better than Devon Street was (and I liked Street here), and Devon has stuck around in the NFL and will continue. But I think his combine numbers wont make people draft him first round.
