You can't just take away all the good plays in a game and say "OK, so aside from all these big plays, we didn't do that well." We all know what happened in the Missouri game. We lost our momentum in the second quarter, due to some streaky play from our understandably streaky QB. Then once we grabbed that last touchdown early in the 3rd, we completely shut it down and no longer tried to even do anything but hold on to victory.
And we're not talking about 2 good games. We're talking about 2 good games against the 4 or so top teams that we played. There were a LOT of good games, but most people are going to dismiss Colorado and Washington and Kansas State and the like. So " 2 good games? That's all it takes to make it another year? " - a little overdramatizing that particular statement.
Know what happened against OU? Taylor was injured. Kansas? Taylor was injured. Iowa State? Cody was playing. That and the defense gave up a ton of points. A&M? Taylor was injured, and Cody was playing. Yeah, there were a lot of other things that went wrong in those games and no coach/player can be exculpated from blame completely. But the overriding factor that set us back in all those games was instability at the quarterback position.
