Because we didn't get the benefit of the doubt on most calls. The interference call was legit and by the book, pushing off is EXPLICITLY called out in the rule book as a form of offensive interference. On the holding call you can clearly see the OL has gripped the defender's jersey and is dragging him down. On the Hasselback tackle the rule was called exactly the same way it was called against he Steelers on consecutive games in the regular season, I disagree with the rule but that is consistent with how they caught it. Meanwhile there was a catch and fumble that could have been recovered by the Steelers that was blown dead and incorrectly ruled incomplete, and a block in the back in Roethlisburgher after his second interception that went completely uncalled.
Simmply 100% BS to say most of the calls went for the Steelers. The Big Ben TD was questionable and went for the Steelers, the Hasselback tackle is a bad rule called correctly that went for the Steelers, and then you've got the fumble and block in the back. So that 4 questionable calls, 2 went for each team.
It is also important to point out -- the penalty was not called because he tackled Taylor low. The penalty was called because he CUT #26 in his attempt to get to Taylor. The rules specifically say that a Defender (which Hasslebeck was at this point) cannot Cut a BLOCKER (which #26 was) belowe the knees. That was the penalty that was called.
I personally feel that penalty was very weak as it was not Hasslebecks intention to take out the blocker, he was going for Taylor. But by a strict interpretation of the rules, he did break the Cut rule when he dove in front of #26.
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.
By the book it was offensive interference. It is only offensive pass interference if the offensive player initiates contact. But since the defender was holding him the whole time that was not the case. If you only watch the last second, I could see why the call was made. But by the book, it was not the right call.
