Njoku is better than all of those guys and he has barely scratched the surface.
He's not, those guys actually have film to back up their physical attributes. Bucky Hodges is similar to Njoku, only he has caught almost double the passes in his career. Jake Butt is a complete tight end, he can play both inline and split. Did I mention that both of those two players can block, something Njoku can't do? I think David is the kind of player that a GM falls in love with, based on how he looks, and his combine, but the kind of team you want to play for will look at his film and ask some pointed questions. How can a guy this athletic, this talented be a nonfactor for most of his career?
