For me it was our D's performance against MSU's running game. Now MSU didn't do much throwing the ball either but you could easily say Lewerke was wildly inaccurate and we were fortunate they had a OL downfield that negated the one TD pass. Other than the one run by the backup QB, they didn't do much against us running the ball.
Honorable mention was the staff's willingness to put in Martell in when in the red zone and third would be Weber running. Don't know where he is with his early injury but he looked better this game than any other so far this season. We need his power running between the tackles.
