The Dallas Cowboys at 5 wins and 1 loss so far with Prescott in command is a think of beauty. I don't think there is enough reason to risk putting Romo back in the starting line up. The tone of a game is set at the onset and if his clumsy, accident and injury prone ass drops the ball or needs a stretcher, I'm convinced the team will suffer another tick in the loss column.
Prescott has earned his place at the table. Romo can wait in line if you ask me.
