If DeMarco Murray is retained by the Dallas Cowboys this offseason, then this whole conversation could be meaningless.
But it's looking more and more like Murray will be allowed to test the free agent market, where he'll surely get a better offer than what the Cowboys are willing to/can pay Murray after he posted the best single season by a running back in franchise history last season.
That would probably lead the Cowboys to draft a running back to replace Murray and bring in a veteran to platoon with said rookie. Coincidentally, the Detroit Lions released Reggie Bush on Wednesday. Hmm.
Bush would be a nice platoon to any running back as a great pass-catcher out of the backfield and a guy who has gotten bigger and stronger over the years and become a better straight-ahead runner, as well. Oh, and there's that whole thing about Bush's former offensive coordinator in Detroit, Scott Linehan, being set to enter his second year as the Cowboys' offensive coordinator.
Under Linehan in 2013, the 29-year-old Bush, who's soon to be 30, had one of the best years as a professional. He posted 1,512 total yards of offense and eclipsed 1,000 rushing yards for just the second time in his career, while adding 54 receptions. He scored seven touchdowns.
Again, Bush isn't a starter-quality back anymore, but as a reserve to a young stud like Todd Gurley or Melvin Gordon, you could do a lot worse.
