Murray is really good when he's healthy and they use him. Unfortunately, the cowboys have some of the worst game management in the history of football atm. So even if they luck out and the planets align for this one game, they'll fuck it up next week.
Who the fuck runs the ball constantly when they're down and need to catch up fast, and then throws tons of short passes when they're looking to eat up clock. The cowboys, thats who. Fuck. Plenty of teams are bad, but the cowboys just play the game fucking wrong most of the time when it counts for the last few years.
