Any of these guys would be a great pick, however, we dont know what any of them will ultimately be at the next level. The team drafting them and the offensive scheme they are playing will make a difference.
Smith could be great, but will he hold up? I cant take that chance, its the NFL, not the NCAA and players are faster and stronger here.
Chase is a better version of Parker. I can see us trading Devante if the pick is Chase.
I like Waddle best as he is the swiss army knife Flo loves. He is a gamebreaker in so many ways. A Parker, Gesicki, Waddle, Fuller line up has to look tasty to Tua.
That said, you cant go wrong with any of these picks. Pick the best of whats available and make it work.
