True. Or it could have resulted in a few more losses. The thing that people often forget is that being more aggressive doesn't guarantee positive results, otherwise everyone would do it (even KF).
Generally speaking, a more aggressive strategy increases the VARIANCE of outcomes. That is, it raises the ceiling, but it also lowers the floor.
Iowa scores 2.19 pts/drive, 74th in the nation (oof). If they employ more aggressive strategies (e.g. taking more deep shots, which is a low-percentage play with a high reward), they have more long TDs, but likely also more 3-and-outs, so fewer FGs. Those things balance out, so the overall number is not guaranteed to go up. Employeeing this strategy game-in and game-out would lead to more really good games, but also more really bad games.
We see that with Brohm from Purdue. I actually really like him as a coach; but in the last 3 seasons he has lost games to Rutgers, Eastern Michigan, and Nevada that he absolutely should not have lost, and probably wouldn't had he not been so aggressive. But he has also played some really good teams very tough for that same reason.
Obviously there is an "optimal" level of aggression that KF probably falls short of. But his strategy ensures consistency, and if the talent-level is high enough, helps us reach our potential (Goliatch-strategy). I think many on here would prefer a higher variance strategy (a few more 10 win seasons even if the cost is a few 6 win seasons). After the Wisconsin game, I just wanted to see Iowa lose differently (I was sick of watching the same old plot unfold).
