Broncos RB C.J. Anderson did enough behind an offensive line that struggled mightily at times in an offense that couldn't find its rhythm over the season's final month to open the offseason as the starter. What happens next, however, will be a test of his football maturity as well as his preparation given success can often be more difficult for some to handle than adversity. Montee Ball, too, has promised to return "ready to win the job." Ronnie Hillman has plenty of untapped potential as well, even as the Broncos keep waiting for the career light to go on with their former third-round pick. They thought it had when Hillman had two 100-yard games in a three-week span in October only to have his season derailed by a foot injury.
Anderson probably holds the most risk of the top 12 running backs heading into the offseason. He was tremendous down the stretch, but there's a new regime in town (though he's considered to be a good fit for new HC Gary Kubiak's zone-blocking attack). Remember, he didn't keep himself in top physical condition last offseason, so that's something to monitor this spring and summer.
