Free agent running back Lance Dunbar is visiting the Rams today, a source tells ESPN.com’s Adam Caplan (on Twitter). This is Dunbar’s first known visit since free agency started six days ago. 
Dunbar was buried on the Cowboys’ depth chart last season and had just nine carries on the year with one score. He added 16 catches for 122 yards. Dunbar was never a starter in his five years for the Cowboys, but that was the least amount of burn he ever received in a healthy season. Even when he played in only nine games in 2013, he still managed to get 30 carries (he averaged 5.0 yards per carry in that limited sample).
The Rams could use some depth behind Todd Gurley. Currently, he has Malcolm Brown and Aaron Green – a pair of former undrafted free agents – as his understudies. Dallas’ level of interest in a reunion is unclear, but if Dunbar were to return, he would be stuck behind Ezekiel Elliott and Alfred Morris.
