Smart kid (graduated after his junior year).
True breakaway speed. He will run a true 4.4 at the combine (if invited) and could possibly break under that (which he has as timed at Auburn).
He's physical freak. Great arm-span. Can jump through the roof.
Now the bad news.
Questionable hands. Has dropped plenty of easy throws in his college career. Lets the ball get to his shoulder pads too often instead of catching it with his hands. Not the most talented at adjusting to the long ball in the air if the throw isn't near perfect.
I'm not comparing him to Julio Jones because we already know what Julio Jones can do in the NFL, but Jones had many of the same questions coming out of college.
Is Coates worth a 1st round pick IMO? No.
A high 2nd? No.
A mid to low 2nd? I think that would be decent value.
A 3rd? GREAT value.
