Because deflated footballs or not, they still would have destroyed the colts. Nothing can change that.
I'm not endorsing cheating obviously, but the patriots were the better team.
Look at it this way. Lebron with PEDs would trample me in a 1 on 1 pick up game. Lebron without PEDs would trample me in a 1 on 1 pick up game. One is cheating and the other isn't, why break the rules when not necessary? Before you say that I'm not a pro ball player, keep in mind that the Colts aren't a real NFL defense.
Sure they beat the Hawks but every given Sunday is the name of the game. Shouldn't have to break rules to get there. The Colts aren't the only team that they've done this against and a history of cheating, murdering, and stealing was taken into account!
