FRISCO, Texas -- Since he became the Dallas Cowboys' starting quarterback in 2006, Tony Romo has never had any competition.
Every backup has been a former starter no longer quite good enough to start such as Jon Kitna, Kyle Orton or Brad Johnson, or clear subordinates the team never really wanted to see in a game.
The Cowboys have been Romo's team no matter the circumstance or the coach for a decade.
Those days have ended.
Dak Prescott, a rookie taken in the fourth round with the 135th pick, has played so well no one knows for sure whether Romo will ever start another game.
