I respectfully disagree. First of all, every study that has analyzed the decision to go for it on 4th down has demonstrated that "conventional wisdom" is incorrect in many cases. From a purely mathematical sense, both decisions to go for it on 4th down were correct, at least according to this analysis.
For the first 4th down decision, we had forced a 3-and-out on MSU's opening drive. We then had marched down the field and had successful plays both on the ground and through the air. We had the Spartan defense on their heels and were facing 4th and 1 from the 18. With the way our defense has played this year, I think the aggressiveness of going for it was warranted.
For the second decision, punting from MSU's 42 yard line is no guarantee that we pin them deep. We were obviously outside of FG range. This is that "no-man's land" area of the football field where being aggressive on 4th down is often the right call. Yes, the outcome of the play (interception with a long return) was disastrous, but that doesn't make it the wrong call.
I have no problem with either decision by the coaching staff. And I certainly don't believe that either decision cost us the ball game. The more critical reasons for the loss was that our OL failed once more to open up any running lanes, our RBs didn't run effectively with what running lanes existed, and Ramsey had arguably his worst game as a Wildcat, with poor decisions and inaccurate passes all game long. We didn't execute plays as a team, but I don't think we lost because of our coaches' in-game decision-making.
