I'm sure other people were doing things but not the that level.Why? It pretty much seems like something that a bunch of teams have probably done, but only NE was stupid enough to get caught for. The Pats were the only team to steal sideline signals in NFL history?
I personally think it's the opposite - people being it up too often.
Since Spygate, NE easily has the best record in the NFL. The Pats were the luckiest play in NFL history from being 19-0 and have won to two Super Bowls since it happened. Two plays from having five championships in like 11 years.
Personally, I don't think anything is hurting his legacy other than idiots on the Internet. He's playing at as high a level as ever during the regular season like 12 years later and he constantly makes small white guys look like Pro Bowlers.
