Talk about homerism...
Back in reality, the Steelers beat the Patriots straight up and it probably isn't even close. While the Patriots can claim an advantage in QB, TE, K and perhaps a couple of other positions (as for guard, Alan Faneca can match up against John Hannah), the Patriots probably lose at virtually every defensive position matched against the Steelers.
You can take almost any other position and the Steelers all time team would stomp the Patriots, specially in depth. Take for instance RB. Who are the Patriots going to throw out there? Jim Nance and Mosi Tatupu? You want to match those guys against Harris and Bettis? At WR the Patriots can send out Moss, Fryar, Brown and Morgan but that pales in comparison to Swann, Stallworth, Brown and Ward. It's like this in almost every position and that's just against the Steelers. It'd be easy to do the same thing with the Cowboys, Packers and 49ers.
Against the field? The NFL all-time team would win by 50.
