PF, you are delusional if you think this only happened once. I remember watching the postgame interviews after the Steelers lost to the Pats in a playoff game by 3 points a few years ago. The Steeler being interviewed said "It seemed like they were in our huddle, they knew everything we were going to do". He had no idea what was going on as this was a few years before the cheating expose came out. And the Pats went on to win the SB.
Yeah ... In 2001, I remember Troy Brown taking a punt back to the house ... and then a blocked FG for a score ...
I wonder how the Pats knew the Steelers were going to punt .... I wonder how they figured out they were going for a FG.
