ESPN Dallas believes the Cowboys are higher are RB Lance Dunbar than Phillip Tanner.
With free agent Felix Jones likely moving on, Dunbar and Tanner are currently penciled in as DeMarco Murray's backups. They could stage a camp battle -- along with whatever other talent the Cowboys add to the position -- for the No. 2 gig. It's worth noting that Murray has missed nine games in his first two NFL seasons and also had his first two seasons at Oklahoma marred by injury.
