We won 2/3 games this year with Romo playing quietly without having to pass for 300 yards and multiple TDs.
As for the OLine, come on. It's not THAT bad. It's funny how no one mentions the job the OLine does for the positives during a game when they allow Romo to have time to make a comeback.
The OLine played an average game vs. the Giants. Not good but not bad either. They gave Romo a fair amount of time...you don't make a comeback like that without having time in the pocket.
