For me, Campbell is a Top 40 player. I definitely see your concerns, and the worry is real if he's just a gadget player or not. That's the fun of evaluation - was he limited in his routes by scheme or ability? I want to say Campbell had like the 4th best shuttle time of the combine, so I think the change of direction skills are there. So that's where you have to be really comfortable with the pro day/individual workouts. How does he look running your route tree? Can he whiteboard the option route concepts? I've got no clue on either of those, so I'm betting on the athlete right now.
