I think both the Dallas and Minnesota offense will move the ball but I think Dallas is playing better defense at the moment which is why I give them a very slight edge. Dallas,of course, can completely kill that edge if they commit too many penalties like they did last week against Philadelphia. Potential touchdown drives turned into punts and field goals because of penalties last week and we can't afford that against a team as talented as Minnesota.
Many people are gonna place this game on the shoulders of Brett Favre but I think the Minnesota offense will go as Adrian Peterson goes. If Dallas is able to shut down the run and make Minnesota one dimensional like they did with Philadelphia then it will be extremely difficult to get consisitant offense going with Ware, Spencer and Ratliff being able to focus solely on rushing Favre. Minnesota has to play balanced offense with a heavy dose of Adrian Peterson and play action to counter that vicious Dallas pass rush.
I think this will be a close game that will probably be decided by less than a touchdown. The winner is going to be the team that doesn't make mistakes. Obviously turnovers are one such mistake but I'm talking about the little things to. Penalties, dropped passes, etc. Mental Mistakes. Whoever wins this game will do so because they were mentally focused.
