I have many of the same critiques I had of Kevin White coming out. He traps the ball way too frequently against his body, neutrilizing his height and wingspan. He doesn't play 6'5", but like tall guys doesn't have the quickness of a Antonio Brown even if he proves like Kevin did he has the 40 yard speed(long strider).
He for sure has some of the Tampa WR, Evans.
I like him, and I'm sure you are right if he runs 4.4ish he will shoot up boards, but he didn't show WR skills in college. He just showed athlete skills, and that is always concerning making the jump. Trapping the ball against his body will not be good enough, there will not be that space, and he either learns to pick cotton like Jeffery or he will bust, or be moved to a slot TE/hybrid guy you just get the ball to quick and annoy defensive backs who have to tackle him.
