Pelini said in the middle of the year that they had originally thought Cody Green was going to be the starter, not Zac Lee, and we saw throughout the first several games that Cody Green was solidly the second string QB.
I can buy the idea that the run/pass ratio shifted when Martinez took over for good, but I don't buy the idea that their offensive philosophy changed. Bo has wanted a run-first offense since he came here, and Martinez is the first QB we've had that has actually enabled that. We were recruiting Jamal Turner and Bubba Starling and Brion Carnes BEFORE Taylor Martinez won the starting job, and those guys are a clear reflection of the offensive philosophy we showed this year.
If you were going to pinpoint where our offensive philosophy changed drastically, I'd look more towards the middle of 2009. The offense tanks against Texas Tech and Iowa State, and things start changing. First, Cody Green gets a couple starts at QB, largely because he is a threat to run. When it becomes clear he isn't ready, we go back to Lee, but in an offense that is focused primarily on power running, because it played to our only strengths and minimized our turnover troubles. Our one QB recruit, Tyler Gabbert, who would have fit the Joe Ganz offense, decommits, and we follow that up with commitments from running QBs such as Turner and Carnes. When we finally get healthy and have time to do install during bowl practices, we show a CLEAR move in the direction of the spread option during the Holiday Bowl.
This shift in philosophy has been in motion for a long time, it didn't happen overnight during fall camp.
I'd also be a lot more willing to listen to these QB/offensive philosophy arguments if at any point in this season Zac Lee or Cody Green actually looked better than Taylor Martinez. But they never did.
