Get a load of this guy:

He won, so he’s allowed to troll. Those are the rules.

If you have no idea what Belichick is referencing here, he’s going back to these comments from 2018, when Johnson criticized the Pats for being a fear-based organization:

“They’re successful, but when they go to interviews, they act like fucking robots. Hey, stop being a dickhead. We can be cordial for a little bit. You only get to do this job one time, so let’s have fun while we’re doing it. Not to be reckless, but I’d much rather have fun and win a Super Bowl than be miserable and win five Super Bowls. But hey, it is what it is.”

That’s the context. Belichick pulled off a nice troll job after this win, but he’s still a cheater.
