When you are in a two party system you'd be surprised what your mind will do to either believe or deny as long as your team wins. You don't care if they cheat or lie as long as they win. You might know they are cheating or lying but you'll still deny it to the other team's fans because you see how much it gets under their skin, and afterall it's a sport because their are only two teams.
I always compare talking to a Trump supporter about his crimes to talking to a Pats fan about Bill Belichick or Brady getting caught cheating red-handed. Not only do they not care, they are confused as to why they should care. It's their team, nothing would convince a Pats fans to start rooting for the Giants.
