The Denver Broncos don't have many obvious holes on their roster heading into the 2013 NFL Draft, but they do have a handful of pending free agents on defense, and could stand to get younger.

SB Nation's Matthew Fairburn released his latest mock draft on Monday, and he projects the Broncos to select South Carolina safety D.J. Swearinger with the 28th pick:

D.J. Swearinger is a force in the secondary. He's got a ton of athleticism and plays the ball in the air as well as any defensive back in this class. Swearinger played some cornerback and safety while at South Carolina, so the Broncos will have some flexibility in how they use Swearinger.

The Broncos also have starting defensive tackles Kevin Vickerson and Jusstin Bannan up for free agency. If any of those players walk, they could turn to someone like Sharrif Floyd or Jesse Williams. Denver is expected to be another Super Bowl contender next season, so it can afford to simply go BPA in this spot.
