His metrics are not that far off from Calvin Freakin' Johnson. If he dominated college and showed the routes/hands Megatron did he'd be in the discussion with Saquon Barkley on who to take first overall.
This is a 2nd rounder with upside but a fit day 1 as a roleplayer that fills MANY roles. He will be useful day 1 without being a polished receiver due to his speed, rushing ability, run blocking, and special teams.
He is much more athletic than TWill overall (vertical, broad jump, etc) and obviously the speed difference gives him a completely different role that compliments Dez rather than conflicting with it. TWill's game is short/intermediate and being a body catcher is catastrophic in those situations. Being a deep ball catcher is different.
There are other safer picks at receiver this draft, but they clash with Dez/TWill/Beas/Witten rather than compliment them.
Some other options are Deon Cain, James Washington, Anthony Miller, Antonio Callaway. Ridley or Moore would be terrible choices at #19 IMO. Burning #19 on a WR is not good.
