The dude is gonna get his ass kicked at the line of scrimmage by pro corners. Unskilled route running and being undersized does not make for a winning combination. And a 4.41 isn't exactly "blow your mind" speed. It's fast, don't get me wrong, but people are making him out to be the next Usain Bolt.
In all honesty though, he won't "suck".. that was sour grapes after Florida beat Alabama last year (even though he didn't play, I hate everything Gators). He'll be an elite number two receiver, or a medeocre number one. I see him as a Lee Evans type.
