In all fairness, as a Steelers fan, when I saw the replay I though the official had no choice but the make the call -- most of the so-called "questionable" calls in the game look right, or at least justified, on replay.
Honestly, I thought the holding call could have gone either way but I do think it was a hold. However, the calls the whiners are picking on were the same way - on the borderline but most likely correct. We had a ton of calls like that against us too - like the Hartwig hold, the fact that Gandy held Harrison all freaking game and it wasn't called, the 1st Fitz TD (where the nose of the ball touched the turf, the Ben TD review, Ike's roughness penalty on Boldin, Harrison's choke slam (which was instigated by a punch to the nuts), and the first Warner fumble/incomplete pass (which arguably should have also been a fumble). However, (take note Seahawks fans) good teams overcome this like the Steelers did.
