Assuming perennial Pro Bowler Champ Bailey stays healthy, free-agent pickups Tracy Porter and Drayton Florence will be competing for one cornerback slot. Another position on the depth chart figures to go to fourth-round pick Omar Bolden, who can also return kickoffs. That could leave second-year CB Chris Harris and third-year CBs Syd'Quan Thompson and Cassius Vaughn competing for one slot; of the three, Harris appears to have the edge because he played nickelback last year and is the only one of the Broncos' younger CBs not coming off an injury.
