on that bizarre play, i can see why the coaching staff got on the field a bit...it was a huge 3rd down, and they thought they just hit the QB and forced an incomplete pass, along with intentional grounding.....yet the ball went backwards, so it was actually a lateral and the play was still live.....so the coaching staff figured it out and had to back off.......
the fact that it was a lateral actually helped ASU on that play.
still, there is no excuse for allowing the coaches on the field, especially after already receiving a sideline warning a few moments earlier in the game.
