Jerry Jones wasn't ready to say Cooper Rush could be the Cowboys' backup to Dak Prescott despite the rookie's play. "I'm just glad to see Rush taking advantage of his opportunities out there," Jones said. "Wouldn't want to get ahead of ourselves in any way here. And the other thing is that we have a lot of confidence in (Moore), his ability to be able to get in there when we would call on him with the personnel around him and get the ball in the right places."
