It's a consistent comment made across multiple analysis.
The dude is raw as hell. He's far from a complete WR. He's got a lot to clean up before being an effective NFL WR. Multiple analyses have said the same thing - his route running and his route tree need expansion because he wasn't asked to run a lot of NFL style routes and when he did, they often lacked precision. He worked in the slot much of his time at UT and sometimes in motion as Heupel wanted to keep DBs off of him because he struggled at press and could be bumped off routes easily. What do you think he's going to see in the pros?
But he runs fast and beat up Bama. So we have to take him at 26. LOL. You guys just fall in love with speed and ignore everything else I guess. Dude has major bust factor at 26. He'd be one of my more disappointing choices at 26. I'd rather take one of the TBs at 26 and I loathe the concept of using a first round pick on a running back.
