Losing in the last 4 seconds against PSU was an offensive "no show"? Do you want to reconsider at least that one?
Field position, down and distance, the personnel package in the game, called formation and the actual play called in the huddle, dictate what audibles that are possible on a given play, if any. In a Pro Offense, the majority of QB audibles for a called run play are more "point of attach", side of the ball with better block up numbers plus the corresponding O-Line blocking calls. For a called pass, mostly a change of hot routes on pass called plays once its determined to be against man, 1, 2 or 3 deep safeties.
HC and OC "the buck stops here" argument is always an easy call to make. Its a business, and I believe Kirk and Brian accept that reality.
Still, with the same coaches and players and roughly the same game plan from week to week (like most teams across the country with an established identity) that stomped OSU and Nebraska and beat Wyoming, North Texas, Iowa State, Illinois and Minnesota. So, the players didn't win theses games, the coaches did?
Ask the players after they lose the game who they blame. They know that they rarely lose a game in which they have executed the game plan perfectly. They blame their individual mistakes, their units mistakes, the teams mistakes or give credit and respect when its due, to the opponent.
Players play, coaches coach, and in the end, share the responsibility for the outcome. In these forums, loyal fans try to understand and make sense of the wins and losses we see, haters hate...I'm guessing you are a hater.
