There are bad calls in every game.
Good teams win despite those calls.
interviews at the end of the first half by both coaches said the same thing: players need to settle down - Pittsburgh did, Seattle didn't...Dont' forget the 6 points the field goal kicker cost them. And the special team for SEattle clearly messed up in atleast 2 instances where they could have knocked that ball inbounds. No, Seattle didn't deserve to win and Pittsburgh made the big plays (loved that throw from EL to #86 - THAT was the biggest play of the day and most impressive)
And, sometimes, less than the best win because of bad calls, too. ;-P
