I was most impressed by the variety of the throws. It wasn't just a compilation of fast wide receivers outrunning overmatched defenders to get under deep balls. You saw fastballs into tight windows, touch passes dropping over defenders' fingertips, and some nice zip downfield.
Obviously in HS football, the best athlete ends up under center a lot to make sure he maximizes touches, but I get the feel this is a real QB. And if the JT experience has taught us anything, it's that a qb skills can be superior to raw physical gifts in the right offense.
