Romo is no longer defendable - he needs to put his team in the Super Bowl.
Ask yourself this ; in the biggest game of their career - Eli , Peyton , Brady, whomever - would they only throw the ball 19 times ?
Romo's 19 throws v GB was a scared display.
They would if they had an OL like the one the Cowboys currently have and if they had a back like Murray.
Eli:
2006 vs Carolina 18 attempts, 10 completions.
2008 vs Cowboys 18 attempts, 12 completions.
Brady has done it too. Payton would probably never do it. One of the knocks I have always had on Payton is that, like Farve, Fouts, Marino and others, he has never really bought into the run the ball mentality. Payton has always, IMO, felt like he could win it by throwing and he has won a lot of games but I think it's cost him in big games. Balance wins. Once you define yourself in one way or the other, you become easier to defend.
