The only issue I have is this: Those were the only two PI calls the entire game. For all 4 quarters, and leading up to that in OT, the refs swallowed their whistles and held onto their flags, letting the players play, and waving off subtle PI (both teams, both sides of the ball), to then decide to be more strict with the rules, that's what has a lot of Bills fans, and Sean McDermott, upset.
But the fact also remains the Bills had several chances to win the game, and didn't.
In every way I can see Seattle going to and winning the SB, but their fans are also well aware of this: This win over SF could bloat their confidence. Also, virtually every game they've played against the Rams for the last decade has been a battle, if that's who they play. I'm sure they will be ready, but fans must know the history between these teams, dating back years.
