The Denver Broncos have released their depth chart in advance of their preseason opener at Dallas this week and quarterback Tim Tebow is listed as Kyle Orton's backup. Tebow has been in more of a contest with Brady Quinn for the No. 2 job than with Orton for the starter's role. Orton has been taking almost all the first-team snaps with Tebow and Orton sharing work with the second and third units. Von Miller, the second overall pick in the draft, is listed as the starter at strongside linebacker and rookie Rahim Moore is the starter at free safety. Rookie Orlando Franklin is listed atop the depth chart at right tackle. Source: Associated Press
