ENGLEWOOD, Colo. -- The countdown to this year’s NFL draft is in the final days, with the Denver Broncos poised to use 10 picks to create the team's 2015 draft class, whether that means packaging some for a trade or simply picking the 10 players they believe can pump up the roster.

So, with the bulk of their work in free agency done, this is the eighth and last of a position-by-position look at where things stand on the roster and which draft prospects could be a fit for the Broncos.

Today: Defensive backs

At the moment: This may one of the more difficult positions for a new arrival to carve out some playing time given Broncos sent three of their starters in the secondary to the Pro Bowl last season: cornerback Chris Harris Jr., cornerback Aqib Talib and safety T.J. Ward. Bradley Roby played 75 percent of the team’s defensive snaps last season as a first-round pick, and the Broncos want him to play even more this season, so much so they are considering the idea of playing him at safety in the base defense at times.

Cornerback Kayvon Webster played in situational work last season, as did safety David Bruton Jr. and cornerback/safety Omar Bolden.

Need factor: The free safety position is open after Rahim Moore’s departure in free agency -- he signed with the Houston Texans -- and that leaves just more than 1,000 snaps of work from a year ago unaccounted for this time around. Bruton has said he hopes to snag the starting spot.

However, if the Broncos follow through with the plan to play Roby some at a deep safety spot in the base defense, then the Broncos are looking to fill the jobs in the nickel (five defensive backs) and dime (six defensive backs) packages. And it is always a position of need in these pass-happy times, as Broncos executive vice president of football operations/general manager John Elway has consistently said with the team’s defense spending most of its time these days in the nickel and dime that “you really can never have enough corners, guys you feel good about in coverage."

So that certainly means they would take a long look at the defensive backs on the board with any of their picks, including in the first round.

Names to keep handy: The Broncos, like everyone else in the league, don’t believe the safety crop is all that good overall in this draft, but the team does feel like there is some value to be had in the middle rounds at the positions.

Wake Forest cornerback Kevin Johnson, Connecticut cornerback Byron Jones and LSU cornerback Jalen Collins would all warrant early attention from the Broncos. Johnson would be a prime target, but the Broncos, with the 28th pick overall in the first round, are not expected to have a chance at him.

Utah’s Eric Rowe is another prospect who will cause the Broncos to pause down the board a bit. However, given he's just over 6 feet tall and 205 pounds, Rowe is just the kind of cornerback who rises up the board during the draft weekend.

Alabama safety Landon Collins is the top safety on the board for many teams, but several personnel evaluators around the league do not believe he is quite worthy of a first-round grade -- though many expect him to be selected in the opening round, perhaps in the upper half. But among the safeties with grades worthy of the first two days of the draft -- rounds 1-3 -- are Arizona State’s Damarious Randall, Virginia’s Anthony Harris and Fresno State’s Derron Smith.

So, when all is said and done in a Denver draft class that currently has 10 picks in it, the Broncos will have at least one cornerback in the mix -- perhaps more if the board falls that way in the middle rounds -- and they do have some safeties they like down the board who they believe could contribute, at minimum, immediately on special teams.
