17. DeflateGate (2015):
The New England Patriots became one of the most hated teams in the NFL because they were caught doing several questionable things. Everybody hates a winner. But it was also the fact that the Pats didn’t mind breaking the rules. We saw this with the SpyGate scandal. They took things to a new level in the 2015 AFC Championship Game. New England played the Colts, shellacking them 45-7.

However, one of the big takeaways from the game was that the Patriots cheated by using underinflated footballs. This was supposed to take the air out of the ball for the Colts’ passing offense. The fact is Brady specifically requested them and received a four-game suspension for his troubles. In the end, he came back to win the NFL MVP award. so he got the last laugh but the Pats became even more notorious.
