To be honest I was surprised he was still there. Personally though I don't quite see the hype surrounding him, granted I only watch the "vs." Videos on Youtube and don't have access to All-22s which makes evaluating WRs and DBs pretty hard, but at USC he primarily ran hitches, tunnel screens and Gos (at least in the games I've seen). While he is ok after the catch its hard to judge his route running for me, which should be by far his best trait according to numerous outlets, once he ran a different route his route running didn't wow me though.
Then again Daniel Jeremiah and other outlets have him ranked really high and sometimes even as the #1 WR. I think DJ even has him in his top 10 overall, I on the other hand am just some random weirdo on the internet so he'll propably turn out really good.
