It's not ridiculous at all. It's a testament to how frost teams have continued to fold time and again after a big swing in the second half of a game.
Option 3 didn't exist because I was pointing out that the 60% stat doesn't apply equally to every situation where you have the lead. That's because you can't just say we have the lead so we should try this 60% play. The situation was poor. Keep the momentum and make northwestern drive the field and climb back into the game.
Even if you succeed and drive for another score, is 18 enough? Northwestern obviously plays differently at that point so who knows. Personally I just think the risk wasn't worth the gain based on what was happening to that point in the game. The numbers only tell part of the story.
