He may very well be great, but he was still considered about the same lever prospect as Josh Dobbs and Anthony Jennings, and both of them have played more and don't have near the hype. Jeremy played in a great offense at Carver and he looked really good in the Arkansas game last year when Marshall was suspended. Of course most any QB could look good with Sammie Coates and Duke Williams catching passes.
Again, he may end up being the best QB in the league this year, Dak included, but the amount of hype he's getting now is excessive. I guess people are either going to look really good or really bad in a few months.
