The day after Super Bowl Feb, 2002, Rams WRs Torrery Holt and Issac Bruce said in the local paper that when then came to the line of scrimmage, a NE safety would quietly call out the Rams exact plays.
20-17 Pats somehow held the highest scoring team in the NFL. It was in a local paper hard copy I saw it. I hear they were told to STFU it is bad for the NFL, ESPN, NBC, CBS, Fox, et al. It is scrubbed from the net but I might be able to recover it thru a friend who works with a huge search engine.
There also used to be countless reports of teams taking extra measures to scrub their lockers and hotels and all of that when the Pats were involved.
Sorry Willie it happened (the Rams thing) and it was downplayed, scrubbed, for the good of the billion dollar industry.
