You are right about the play calling after Ballard's airborne sideline play. This MUST BE UNDERSTOOD AND DECIDED OUTSIDE OF THE CONTEXT OF A GAME. You have to ask yourself, "Dan, given the ball on the 1 yard line with 11 seconds (or any other situation under 20 seconds), 1 TO, and trailing by a touchdown, would you prefer 2 plays to try to score or 3? This is not even close to being debatable and I would have considered it to be an utter failure in strategy even if Relf had scored. Put yourself in AU's shoes. Would you prefer to defend 2 plays or 3 plays from the 1? When you are losing by a TD with 10 seconds, you don't have the luxury of running the plays that you prefer to run. Everything is dictated by the clock and giving yourself the best chance to win.
After your TO, it has to be a roll-out pass play, throw it if its open, throw it away quick if its not. With some QBs you can trust them with the option of running it in if its WIDE open. With Relf, he probably thinks every run play for him is WIDE open, so its risky. You have to get your QB to understand this. Then on the last play of the game, you just run your best play to score.
