That was somewhat the case last night as well. There were not many penalties, other than blatant ones that happened right in front of the ref. The only penalty that should not have been called was the chop called against Hasselbeck. And even that wasn't called for his tackle but rather for the blocker that he chopped as he was making the tackle. The refs should have talked that one out a bit and said, the guy he was hitting was the ball carrier even if he did also hit a blocker, so pick up the flag. So one bogus penalty call is hardly enough to say the officiating was the "worst" aspect of the game.
The refs were too much a part of the game. They blew the whistle to kill plays that might have benefitted Pittsburgh too quickly as well.
