I'm kind of on board with the Frazier/Berringer metaphor here. If we could have a healthy Martinez for the Michigan State game, I'd take him in a heartbeat. A healthy Martinez is probably the only guy in the conference outside of Ohio State that Pat Narduzzi's defense is actually scared of.
However, Martinez isn't healthy, and isn't going to be anytime soon. If he gets healthy and gets his timing with the receivers back - then yes, you disrupt the "chemistry," and you play the best player. Just like Osborne did with Frazier in the bowl game.
Armstrong had a great game-winning drive yesterday and runs the option pretty well, but overall, the offense looks more like the 2009 version than it does 2010-2012. And with Armstrong at QB, that's what this game on Saturday is going to be: Hope that Nebraska can score 10 and hold Michigan State to 9.
That said, I'm excited about Armstrong's future. The guys on the radio yesterday were saying he's still not full-speed, still recovering from the knee surgery. If he gets noticeably faster next season, he's going to be very dangerous.
