Dunno, most be home-town biased because I watch every play of every game and I don't see where they're holding more or less then anyone else.
That being said, for years the Broncos were always considered the best OL in the league and also the dirtiest, so I tend to think if an OL is playing very well, people assuming they are holding and clipping and such because they don't think it's possible for the OL to do that well w/o cheating.
on the other "story" Arlen Spector was quoted in an ESPN interview that he first questioned this before the Eagles game and didn't get any response.
Kinda funny, a Senator using his power to try and stong arm the NFL because he thinks maybe his favorite team got cheated...
