Few things I'll point out:
(1) Randy Sanders wasn't kidding about the arm strength and the tight spiral. Everything coming out of this kid's hand was just an absolute bullet, which really was his biggest problem on some of the shorter throws. He's got a better arm than McCarron, at least.
(2) Like how he holds the ball high and tight to the chest. That bodes well for ball security in the pocket, and it's a big part of why he has a pretty quick release.
(3) Decent athlete, and probably good enough to have some successful scrambles from time-to-time, but he's not really beating anyone in the SEC consistently with his legs. We might keep the zone read in the 'book with him just so it can make a transition to Sims easier if it becomes necessary, but it will be lightly used, if at all, with Coker under center.
(4) Needs a bit more touch on the shorter throws into the interior of the field. Too many bullets on crossing routes that can quickly become easy INTs for trailing linebackers and safeties once a ball skids off of someone's hands.
