Having sat up in those sections a few times, I could see this getting put back on the Patriots. Just as the half ends, the security guards set up at the end of the seating aisles to block the stairs and allow the coaches to get a clear path down to the locker room. Some of the coaches run, because they don't have a lot of time to get down there. If security allowed some fan(s) to get in the Steelers coaches way, those coaches would be very unhappy. My guess is that we're going to hear that some Patriots security guard allowed fans to block the Steelers' coaches path to the locker room and that this altercation is all their fault.
