Is there some reason he did not work out at the NFL Combine?

I fail to see ANYTHING in his mash-ups that would indicate he is a viable candidate to be an NFL prime receiver. I watched four different ones, and there is nothing on video to suggest he was much of a play-maker in his own college formations. His own QB rarely looked his way. The only action he gets manages to be unimpressive. He ran a route short of the first down line. HE took a screen pass two yards shy of the goal line and ran straight out of bounds at the two yard line. 

Blah. Blah. Blah.

Yeah, he returned a punt for a TD....but AFTER he fumbled the punt reception.
