Nice cherry picking...
I was at the Minnesota game and wondered why TM was playing the entire game when he wasn't getting it done.
Armstrong was bad against Purdue, no question. What does the Northwestern game have to do with anything? It hadn't been played yet, which makes me laugh that you use this as proof TA shouldn't have played against Minnesota... Did the coaches have a time machine? Is that how they knew not to play Armstrong against Minnesota? And if they did, why didn't they just watch the game so they could watch the handful of plays Minnesota destroyed us on and then we could have defended it.
A better comparison would be more games before Minnesota, which I decided to check on, and this is what I found... Against SDSU, Armstrong was 12-15 for 169 yards and no ints. Against Illinois Armstrong was 8-13 for 135 with no ints. Admittedly he did poorly against Purdue, but the two games prior to Purdue were not bad games at all. No TDs, but no ints either. Do we judge our QBs on one bad game? The first one they have we bench them?
