From a pure scouting perspective, Coleman quite literally checked all the boxes.
1. He was young. Coleman came out a year early and was only 21 on draft day 2016.
2. He was an elite athlete. Coleman wasn't a huge kid at 5'11", 194 - but he posted a 94.4% SPARQ score and a 9.66 RAS with elite explosiveness, agility and speed.
3. He was wildly productive. Coleman had 138 catches for 2,482 yards and 31 touchdowns over his final two college seasons was the 9th overall player on PFF's big board that year.
The problem is there's a lot more that goes into scouting these prospects. Things that fans and media members are simply never going to be fully aware of.
Coleman was/is an extremely immature and entitled young man who didn’t have a great work ethic and struggled mightily with adversity/when things got difficult.
Throw on top of that the unfortunate luck that Coleman had had with injuries, breaking his hand twice and tearing his ACL.
Beyond all of that that (and this one admittedly is tough even for the teams to predict), Coleman was one of those players who did not handle having a ton of money very well whatsoever.
In the end, Corey Coleman the man failed Corey Coleman the player.
