Sure. I'm not much of a scout, but I played receiver so I can at least comment on the aspects of his receiving game that I liked.
Great concentration - A lot of his catches were contested heavily by DBs in close proximity to him (whether this was due to lack of separation or not I can't say, but he managed to pull in a LARGE majority of the difficult ones).
Decent Speed - He pulled away from defenders when he had any amount of open space in front of him (which didn't happen a ton due to the way Michigan runs their offense, but the speed is there).
Plays Big - Again, like I said, he made a lot of key plays for us. 3rd and 4th down catches. I like to see that quality in a receiver.
Lanky - He's GOT to put on weight. For his height I would like to see at least 200lbs on him (I believe he's about 190). An extra 10 wouldn't hurt his speed as much as it would benefit his presence.

As far as a DB, big wingspan, good positioning, and WR hands (for obvious reasons).

Again, I'm probably biased. But I loved watching him play and always hoped Dolphins would draft him (just didn't think he would drop that far).
EDIT - this was in response to someone asking about my take on Tony Lippett
