I used to be a huge fan because of the passion the guy brought for winning. However over time we've seen who he's become. End of the day he's rich, he'll never have to work another day in his life. I think he sees the cowboys as challenge, to try and prove to himself he can win his way, and only his way.
He'd rather lose and potentially get all the credit, than win and have to share it. Which i never understood because with the patriots all they do is give bob kraft credit, and show him a million times a game.
