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 2015 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 second of a position-by-position look at where things stand on the roster and what draft prospects could be a fit for the Broncos.

Today: Running backs.

Wednesday: Wide receivers.

At the moment: There isn't a whole lot of room in the inn and it's already crowded with young players as well, with each of the top three having been the team's lead back at some point in the 2014 season. Coach Gary Kubiak has said C.J. Anderson, who rushed for 648 of his 849 yards in 2014 over the regular season's last six games, should open the offseason program like he's the starter.

But even Anderson knows how competitive things already are.

"I know the talent that is behind me, the talent that could be in front of me," Anderson said Monday. "...I know how [running backs coach Eric] Studesville is in giving everybody a fair-shot opportunity, it's just up to me to take care of business."

Anderson, Montee Ball and Ronnie Hillman were each the team's No. 1 back at times last season. The Broncos also have Juwan Thompson, Kapri Bibbs and Jeremy Stewart on the depth chart.

Need factor: The Broncos will play a fullback in the new offense with Thompson set to get a look there as well as recent signee James Casey, a tight end, so there could be room for a draft addition there. But overall, a running back will truly have to be the best player available when the Broncos' picks roll around for them to select one.

In short, they like the group they already have on the roster and only Stewart is older than 24, and at age 26 he's just entering his fourth season in the league.

Names to keep handy: Georgia's Todd Gurley is easily the top of the class, even coming off of ACL surgery. Several personnel executives said this week Gurley's medical re-check, in Indianapolis, on the repaired knee went well.

Gurley is certainly in the not-going-to-happen zone for the Broncos, but if by some movement of earth and stars in the first round Gurley fell to the Broncos at 28th, or anywhere in the 20s really, he would easily be the best player available at that moment.

In general, there are some concerns over fumbles with a lot of the backs on the board, but in terms of what they would like and where they are picking, Nebraska's Ameer Abdullah would fit the Broncos' new offense -- three 1,100-yard rushing seasons to go with three 20-catch seasons -- as would Alabama's T.J. Yeldon and Minnesota's David Cobb.

Yeldon is a decisive runner who has shown a consistently good feel for where the run lanes are and averaged 6.3, 6.0 and 5.0 yards per carry in his three seasons at Alabama. Cobb ran a 4.80 40-yard dash at the scouting combine, but he is an efficient one-cut runner who went from just 11 carries in his first two seasons combined with the Gophers to 1,202 rushing yards as a junior and 1,626 rushing yards this past season.

Down the board a bit, Louisiana-Lafayette's Ross Scheuerman has shown one-cut ability and has produced with even spotty blocking in front of him at times to go with 57 receptions this past season as well as a 39.0 average on kickoff returns. South Dakota State's Zach Zenner had plenty of work in his collegiate career -- 1,095 carries in his four seasons -- but also had three consecutive 2,000-yard seasons.

Northern Iowa's David Johnson is another high-volume back with 1,007 touches in his career, who has also returned kicks some. A long strider, Johnson showed a quality jump cut in is game video and ran 4.50 in the 40 at the combine at 224 pounds.
