There was unrefutable evidence that Hasselbeck was touched on the fumble. Ben's TD and the pass interference were questionable. Throw in three touchy drive-killing holding calls that went against the Seahawks. Seahawks were penalized 7 times for 70 yards, versus Pittsburg 3 times for 20 yards. If Seattle's penalties were clear cut, they would have no gripe. But reguardless, they lost. Calls are part of the game.
Not that fumble, the fumble they ruled an incomplete pass in the 1st half. The Hasselback fumble was 100% the correct call. Sorry about that, I thought as I wrote that line it might be unclear which non-fumble I was refering to and then did nothing about it.
None of those holds were touchy feely. They were legit holds, especially the "drive killers" which were both on the same OL for nearly identical grips on I think the same defender, he should have learned the first time.
