I'm not gonna say Dallas will beat N.E, but the game is in Dallas, and the Cowboys do belong on the same field with N.E, contrary to popular belief. With that said, Dallas has to run the ball, chew the clock and win the turnover battle, if they do those three things, they have even odds to beat New England. If they don't win at least two of those three categories, they'll get beat by 2 TD's or more.
As good as New England is, they can be bullied. Miami ran the ball down their throats last year and the Colts pounded on them in the AFC championship game last year. Dallas has a very physical squad, they get after you on both sides of the ball, but the fear for Cowboy fans should be the coaching matchup......the Evil Genious VS Bum's Son.....ouch.
