I liked his lengthy Hudl video. He kind of shorts his throwing motion, which seems to limit some of the velocity, but he has really good escapability and feel in the pocket. Very nice touch and good vision to find the open receiver.
However, this isn't the kind of guy that will be a threat to start in his first couple of years. He's going to need some mechanical work to increase his velocity to a Big 12 level. But the stuff you can't coach, like pocket presence and feel, scrambling ability, escaping the pocket, finding the open guy under pressure, etc., he seems really pretty good at.
