#1 - Leavitt threw his final pass out of bounds while inside the pocket. No receiver anywhere near the pass => Intentional grounding...8-yard loss on the play. Ball at the ASU 43.
#2 - AFTER the play, ASU fans rush the field before the game is ruled to be over. 15-yard unsportsmanlike penalty on the ASU bench. Ball at the ASU 28.
#3 - It took 15 minutes to get the fans off the field. 5-yard delay of game on ASU. Ball at the ASU 23.

Sure, #3 is a stretch. But, #1 is legit and so is #2. Having the ball at the ASU 28 on that final play would have been HUGE.
