one of the best, as in top 10. vernon davis could be one of the best, as in top 3. as in a game changer, as in antonio gates or tony gonzales (when he was hot). as in he's a very large, very fast wide receiver, one you can't cover with db (he's too big) or a lb (he's too fast). mcmichael is very good, but he's not a game changer. also, he had some key drops last year, and the off the field crap doesn't help.
re he's unproven - of course he is. every player is at draft time. reggie bush is an unproven running back, would you be ok if he joined the fish?
