I don't have a problem with his personality at all, but I think he's overrated.
He's quick, runs good routes, gets open, etc. But he definitely doesn't have the greatest hands (not NEARLY as bad as Coles though, that guy fuckin SUCKS, lol) and he doesn't do much after the catch. Don't get me wrong, he's a good receiver, but he's not an elite player like Moss/Fitzgerald/Andre Johnson/Reggie Wayne/etc
