When Tony Romo is cleared medically to return from a broken left collarbone, the Cowboys will determine whether the team has a better chance to win by playing its franchise quarterback or backup Jon Kitna. Dallas owner Jerry Jones is optimistic that Romo will be able to return by Christmas. "I want to do anything we can to win the game. Everything," said Jones, whose team is not in playoff contention with a 4-8 record. "Pull no stops out to win the ball game. It would be based on that, giving us the best chance to win. "Now you say well surely, if he's your starting quarterback he gives you the best chance. Well, it would have to do with knocking some of the rust off, too. He shouldn't, it would surprise me, for him to come out and be as sharp as he would have been if he had been playing in all the games." Romo broke his non-throwing collarbone in the Oct. 25 loss to the Giants.
