You should try watching some of the games and open practices. Leidner had some great drives last year as a RS Freshman with almost no experience. In particular, a great drive against Michigan and, of course, the 4th qtr of the bowl game. He would have won that game for us if the special teams hadn't allowed a run back. As it was he took the game down to the last play.
In the spring practices so far Mitch has looked very good. He can throw an accurate long ball. We haven't seen that in Minnesota since Cory Sauter (sp?).
After summer workouts, 30 practices in the fall, and 4 non-conference games (which minnesota will win), Mitch will enter the B10 as a very good QB - a real threat.
I was at several spring practice and came away with the same conclusion as you did. The lack of patience here is something to behold.
