I said this same thing in other threads. The college football landscape has changed. Your name doesn't carry you as much as it used to. You have to allow a coach the time to install their system and this isn't just about calling plays, it's getting the kids to buy into what you are doing as well.
I think Herman's biggest problem right now, is not respecting other teams that in years past would be considered beneath them. The fake punt? What was the purpose of that? Punt, pin ISU deep, we weren't moving the ball great and Texas had the lead and play for field position. Then the 4th down try? Take the points, go up by 7, make us tie. I think if they kick the field goal there, they probably win. Yes, we still punted after that, but that stop completely changed the game.
Not that I dont think ISU ever doubted they could win, but that play lit a fire in ISU, you could just see a "We got this" in our last drive and put UT on their heels.
