The Cowboys have the opportunity to acquire a first-round quarterback at a bargain-bin discount.

That opportunity affords them the chance to work the numbers to reacquire disgruntled Eagles running back DeMarco Murray.

But reacquiring Murray could help the Cowboys if they do take on the Johnny Manziel rehabilitation project.

His return to the Eagles remains unclear, despite the exit of coach Chip Kelly, according to NFL.com.

Johnny Manziel Could Turn Allies Into Enemies

"In fact, Eagles and Murray appear headed toward a stare-down regarding his future with the organization, according to several sources informed of the situation," NFL.com reported. "The division boils down to: Murray's unsuccessful 2015 campaign during which he rushed for only 702 yards, the Eagles' lack of conviction that he's the right back and the massive contract Murray signed last offseason."

Not only is Murray battling Eagles management, but he still has a stigma of playing last season with a lack of effort, as Larry Brown Sports reported in November.

The combination of issues with Murray and the Eagles makes his return less likely. The bigger issue is whether Philadelphia would trade the RB to a division rival.

Dallas witnessed first-hand what happened without a league-leading running back. Defenses ramped up the pressure on quarterback Tony Romo and knocked him out with injuries. Twice.

As much as Cowboys owner Jerry Jones talks about a three- or four-year window for Romo, all the injuries he's sustained suggest a Peyton Manning-like physical decline.

Dallas signing Manziel would remove the pressure from him to produce early and help the Cowboys establish a regimen to help Manziel stay away from his destructive lifestyle. But the chances of Romo staying healthy for 16 weeks seem slim.

Manziel was spotted wearing a Cowboys T-shirt last week, and he was willing to analyze a Mavericks game, ESPN's Tim McMahon tweeted, via Fox Sports.

Cowboys Hall of Fame wide receiver Michael Irvin has volunteered to help Manziel in Dallas, according to The Dallas Morning News.

"There will come a time when he will cross over that threshold and become a great football player," Irvin said, "and I am willing to work with him on that and I hope the Cowboys do get him."

And the best way to help Manziel is to equip him with a punishing ground game that led the Cowboys to a 12-4 record in 2014. Despite all Manziel's offseason issues, he had shown progress and promise as the Browns starter last season.

It's up to the Cowboys to figure out how to make it work.
