Brady and Belichick win another Super Bowl, much to the dismay of the many who wanted to see them humbled. With scores so low, it had to be less fun to watch unless you’re a real student of defensive play.
When one team wins several consecutive or near-consecutive championships, as the Patriots have, there’s a real tendency for folks to resent it. The Yankees had this same problem.
Those who (unlike me) follow sports closely can almost certainly think of other examples of winners being disliked for dominating their sport. It’s a peculiarity of human nature, one supposes.
