Darren McFadden brings the best pedigree, even if he's lacking the actual production part. Joseph Randle may need to do more and talk less, but he's certainly got a spot locked up.
Ryan Williams was a second-round pick of Arizona's just a few short seasons ago and Lance Dunbar catches a mean pass out of the backfield.
In short, the Dallas Cowboys, head coach Jason Garrett and offensive coordinator Scott Linehan have several potentially high-upside options to help fill the void left by DeMarco Murray's departure in free agency, though none are all that compelling.
At least one of those players though, who many in Dallas have assumed would be a lock for the roster, Dunbar, may not be as certain of a spot on the team in 2015 as previously thought.
Bob Sturm of The Dallas Morning News, in answer to a reader's question about Dunbar's future with the team, sounded a potentially negative tone.
"I don't think Dunbar is a given to make the team. But, he does have experience and special teams ability as a coverage guy. I think that is why he got the nod over Ryan Williams last season. It will be interesting who gets that RB3 job this year. They want Dunbar to work, but his skill-set is too limited for me," Sturm wrote.
In three professional seasons, Dunbar, the former undrafted free agent out of North Texas, has amassed 80 rushing attempts for 324 yards, a 4.1 yards-per-carry average, and no touchdowns in 37 games.
The diminutive Dunbar put together a phenomenal training camp last year, turning heads regularly and looking like a lock to make some serious noise once the regular season opened.
That failed to materialize though and Dunbar's biggest contribution for Dallas last season came via his 31 receptions for 309 yards.
It's become something of a running gag in the NFL - these training camp darlings who annually look set to break out after putting together promising offseasons only to then fall back to earth once pads go on and the touches and games start to actually matter.
While Dunbar failed to crack the runner rotation in 2014 as Murray saw the lion's share - and then some - of touches for the Cowboys, Dunbar is right back on pace this offseason, making waves at Dallas' OTAs.
"He was a back that could do everything," Dunbar said of Murray, per Clarence Hill, Jr. of the Fort Worth Star-Telegram. "It was his time. It was frustrating, but at the same time it was what was best for the team. It was working. We were winning. Why change it up? But I feel good about my opportunities this year."
Dunbar, still just 25, is keeping his sights set firmly on a third-down, pass-catching role as his main means of latching onto the Boys roster.
"I'm just competing every day," Dunbar said, via Hill. "Whatever happens (with the starting job) happens. But I know I'm going to have a role. Since DeMarco is gone, there is lot to be done."
As Hill notes, during the recent round of OTAs Dunbar was seeing the majority of the snaps for the two-minute offense, indicating that offensive coordinator Scott Linehan is likely looking at him as the first competitor up for the third-down back role.
Still, history could very well repeat itself where Dunbar is concerned and if Sturm is to be believed, Williams may have just as good a shot at making the roster, presumably pushing Dunbar out at the same time.
While Williams doesn't possess the same type of pass-catching ability as Dunbar - in five games in 2012, Williams caught just seven balls - if he's able to move his way up the depth chart and steal some of the starting snaps from McFadden or Randle, it could push the rest of the backs down and make Dunbar a potentially unnecessary piece of the puzzle.
