Peyton Manning thought the Patriots were cheating as well, according to his former coach

Pretty telling that one of the best in the game thought this.

The New England Patriots history of cheating is well-known, and apparently it's not just the fans that buy into the fact that they create unfair advantages.

According to former Indianapolis Colts head coach Tony Dungy, it even trickled down to quarterback Peyton Manning, who evidently thought the Patriots were bugging the visitors locker room.

"...As Peyton talked to guys who played for the Patriots, some of the guys who came over — whether it's true or not he treated it as true. We didn't have a lot of strategy discussions inside the locker room there," Dungy said, via Pro Football Talk.

Whether the Patriots really did create this advantage or not is unknown, but it is telling when one of the best quarterbacks in the game had to create alternative ways just to discuss his gameplan due to fear of the opposition cheating.
