Not understanding the Keon Coleman hype at all
I share your concerns, but it's not like just people from Louisiana rate him. Many had him going in the 1st and most everywhere had him as a 2nd round pick.
Personally, I don't like the lack of separation and the fact that he never really seemed to dominate a game except against a terrible LSU defense. But, maybe the lack of separation can be fixed with better route running or better technique? I think people like him because he's huge, makes contested catches, and gets YAC. But, I see him as a less quick Treylon Burks who has be very underwhelming in the NFL. I see better value in Johnny Wilson at FSU who you can likely get in the 4th who is much faster and quicker with the same basic skill set.
