“Pushing on his shoulder” to a point. Virtually any time an offensive lineman gets beat by a pass rusher with whom he is engaged, there is some period of holding – this is the amount of time between the pass rusher’s becoming parallel or better with the blocker, and the blocker’s disengaging. This play was no different. What generally determines whether it is called or not is how quickly the defender disengages.
In my opinion, the block in question was in the “hold period” for an awkward amount of time – run that same action 100 times, and sometimes it will be called, sometimes not (but usually not). Something like 80/20 sounds about right. My guess is that the reason it was called in this instance was that the action caused the pass rusher to stumble and ultimately fall to the ground, which is one of the main signals for the refs to throw a flag.
It’s worth noting that Sean Locklear, IIRC, got flagged for holding more than any other player in the league this year. It’s unfortunate – but neither surprising nor offensive – that it cost his team huge when it mattered. The real complaint should, IMO, be inconsistency, as there were several instances of very similar “holds” on both teams that went un-called.
I just rewatched the game last night. There were two outright blown calls: Hasselbeck’s low block (never made contact with a Steeler’s blocker) and Steven’s non-fumble, which is really very clear on replay: catch, step, step, tuck, turn, step, hit, fumble. Anyone who argues otherwise is misremembering or misrepresenting what happened, as he clearly took three steps, tucked the ball, and turned completely around after catching it but before losing control. OTOH, it’s very likely the ball would have gone out of bounds even if the official hadn’t blown the whistle.
Locklear’s hold was a judgement call that usually goes the other way. Roethlisberger’s TD run was insanely close, could have gone either way, and probably made no difference since it would have been 4th and a millimeter if they hadn’t gotten the call. The block in the back on Roethlisberger on the INT return was another judgement call that could have easily gone the other way. Ditto for the holding calls on Seattle’s punt/kickoff returns, but the refs tend to be really anal on returns in general. The controverial spots looked right to me.
The refs didn’t cost Seattle the game; Seattle’s mistakes were the culprits – there were a ton of them. Many dropped passes. Hasselbeck sailing throws. Alexander apparently forgetting how to be a receiver out of the backfield. The 3rd down holding call that killed their first drive (which was completely legit). Awful play by the safeties, which was the key in all three of Pittsburgh’s big plays.
Really, Pittsburgh won because they made fewer mistakes. Neither team played well – a disappointing Super Bowl, all in all.
