Second in an eight-part series examining the Cowboys' free-agent needs.
The Cowboys have arguably the league's top running back in Ezekiel Elliott, so they have more pressing needs in free agency than adding another tailback.
However, veteran Alfred Morris becomes an unrestricted free agent, and that will open a hole on the roster.
The Cowboys are big believers in running back Rod Smith, so he could step into more of the backup role in 2018 without Dallas missing much.
Smith averaged 4.2 rushing yards and 10.6 yards a catch last season in limited action.
