I know he was upset. After the game he was essentially trying to blame the refs saying that they should've been standing over the ball and allowed him to substitute. I argue that he did in fact have time to substitute--that's how you had thirteen men on the field, Coach.
After LSU scored their final TD Dooley throws his headset down and walks off the field. Les Miles had to run him down to shake his hand.
I don't care whether you're angry at the refs or not, show some class and shake hands at the end of the game instead of running off the field.
