Cooper is this year's Donald. It seems like he's getting undervalued but the film doesn't lie. He's THAT good. Not only does he have the talent to be a top 5 WR in the NFL...he is very polished and pro ready.
The guy wastes little to no movement when running routes, he makes explosive cuts on a dime, understands how to attack defenders, and is a top shelf athlete with good run after catch skills.
To put it bluntly, Amari Cooper is the WR prospect you dream about. He is a mix of Sammy Watkins and Odell Beckham Jr.(although he doesn't have the spectacular catch making ability that OBJ has).
IMO, he's a guy that can legitimately come in and put up 1000+ yards and 10 TDs as a rookie.
