There is no use crying about it now, but apparently, Hines Ward grabbed Chris McAlister's face-mask when he got wide-open after Roethlisberger escaped the sack. The following clip has Rex Ryan detailing it:
Watch 1:55 to 2:24. I know that McAlister plays very physical press-coverage, but at least he gets flagged. This was a HUGE play in the game, and it's sad to think that it wasn't legitimate. I've never really liked Ward, but I have respected him. Plays like this make me lose respect for him.
