You cannot say it enough: Tommy Armstrong was a redshirt freshman asked to start last year. Not play backup. Start.
I don't know that Tommy is going to go Hulk-Smash mode this season, but considering all of the factors that went into last season (his knee injury, the scope, injuries on the line/receiving corps, the unexpectedness of his starting role, the rotation situation), we saw a kid who did go 7-1 and make a few sick plays along the way. See the Michigan go-ahead TD--you know, the winning score on the road in one of the most intimidating stadiums in football. If someone wants to say that a Rs. freshman who was expected to play a limited backup role made some mistakes in the time he got, fine, wonderful. In other news, the sky is blue.
My main point is that I think he has a much higher ceiling than Martinez. It's only an expectation; the games will tell the full truth soon enough. But his feel for the option and command of the huddle bode well. (Of course Beck's play calling is going to have a lot to contribute to this conversation.)
The other thing is if we're going to play at B1G championship level, a lot of that is going to come from the defense, and the defense will be helped along by a good-not-great QB who doesn't turn the ball over and keeps the run game chugging along. Speaking of which, we're four deep at running back, including one guy who if things go really right could show up a the Heisman ceremony.
