The refs made more big plays for the Stealers than did the Stealers. More yardage too, when you factor in the disallowed downfield yardage lost and add in the penalty yards.
The Not Fair League got what it wanted. All Stealers fans, players and personnel know the game was handed to them. Few will care.
Between missed TD passes, missed field goals, and missed 3rd down conversions that would have put Seattle in FG range the Seahawks easily left 16 points on the field in the first half on drives that had not one single flag thrown against them. If you want to know why Seattle lost just look at those drives.
