Kyle Orton is eager to learn Broncos coach Josh McDaniels' offensive system, and to work hard in Denver. "Leadership doesn't come overnight," Orton said. "I plan to put my head down and go to work and show the guys what my work ethic is." Orton will lead the league in mini-camps this year. Most teams have two mini-camps, and he's already been through one with the Chicago Bears. The Broncos get an extra mini-camp because they have a new head coach.
