Five Broncos to watch
1. Chad Kelly
He may have the No. 2 quarterback job already wrapped up, but he can lock it down with a productive first half. Kelly will start the game and if he plays turnover free and continues to show a savvy for making plays when having to avoid pressure, Kelly deserves to be the main backup Sept.
