In many cases, players who slip down in teh draft as a result from the combine have been victimized by a stupid system that overemphasizes a small portion of the player.
However in this case, he is a huge question mark, the most harmful player to a school in years, and someone who has not even played 10 colelge football games.
First of all, his 40 yard dash times were extremely poor. He's never been a speedster, but a player with as many red flags as him cannot afford a 4.82 time.
Second of all, quitting the combine shows his true character that has endured despite teh smokescreen of his "changed attitude."
He has wasted his talents more than any player in recent memory. Others have committed crimes, but those weren't quite as intentional of mistakes (tho they were still their screwups). This one he tried to lie to the police, alienated himself from tOSU, challenged the NFL and lost, showed up flabby last year at the combine, used ESPiN to lash out at tOSU, snubbed the senior bowl, and now has failed to even be in peak physical shape in what will be his last shot.
