After watching that one thing that really is clear is he gets beat in slants ALOT. I understand slants are hard to cover in general but he was losing those battles to Miami university and everyone in between. Maybe a little coaching on better technique and standing inside shade a little.
He had good coverage when WR release outside, and used good strong hands when jamming with the correct hand. I think if he turns and runs with his receiver at the 7 yard mark instead of watching the QB he will keep more of his speed getting into stride sooner.
