Concerns for Neal: ball security and blocking, both of which I think Graham will resolve.
Positives for Neal are huge: speed, big play threat, size to handle SEC defenses, and my personal favorite about him is his experience as a WR. I have no doubt CJC is going to split him out, put him motion, and get LB's on him in coverage. He can be nightmare for defenses because of his pass catching ability imo.
If he's used correctly he can be the perfect compliment to Rogers, Hunter, and Patterson (who I'm giving the benefit of the doubt as a major contributor until proven otherwise)
This is the most excited I've been about an offense we're fielding since Stallworth and Washington were here.
