First, thanks.
But that distinction you mention, the one between the way Parcells and Belichick handle things, isn't about winning or preparing the team. Belichick may it is, but he's lying. He's not seriously worried about losing a lead when he's up by 40 in the fourth quarter. If and when he says so, that's just lip service. No, this goes back to his anger about being busted over Spygate, or something else other than preparing his team.
A lot of people in these threads are confusing two issues that have nothing to do with each other. You can win with class, and you can lose with class. You can also win without class and lose without class. Belichick certainly has the right to win without class, but other people also have the right to point out what a jerk he is.
