Comedian Anthony Jeselnik is a HUGE Steelers fan ... so how does he feel about the ESPN report claiming Tom Brady, Bill Belichick and Robert Kraft are beefing behind the scenes?

But the former "Last Comic Standing" host ain't saying it's game over for New England.
In fact, he told us a little infighting is common with great teams like Michael Jordan's Bulls .
