What I saw:
Nice burst. Nice closing speed. Block slipper rather than a block shedder, which could mean a look in the middle over an initial look at SLB. Quick mental reactions to plays - especially the two screens on there (watch his head).
What I didn't see:
Shedding many blocks. Doing anything more than freelancing a gap blitz and using his athleticism to make the play. Get deep in coverage more than once or twice. Looks like he needs time in the weight room.
I like him. He'll probably play next year.
