The Seahawk pushed the defender AWAY from the ball. Contact prior to then was clearly incidental because they ran into each other (you are allowed to put your hands out to lessen impact). The refs have been solid.
I disagree, the refs have clearly been favoring the Steelers, one play after another.
It looked more like they were dancing, than anything else. It was mutual contact. The Seahawhks have been robbed, call after call. This has been disgusting, now the Seahawks are blowing it all on their own. The ref have handed the momentum to the Steelers. It' too bad, they've ruined the game.
John Madden mentioned that Mike Holmgren remembered the head ref from when Holmgren was an assistant high school coach. You don't remember a ref because they're good. You only remember the bad ones.
