The Buccaneers haven't lost any of their primary ballcarriers from last season, but that doesn't mean the position is without question marks.
Antone Smith is an unrestricted free agent who has not been re-signed, but he was a midseason addition who got only 10 carries before landing on injured reserve. Injuries were a problem across the board in the Bucs' backfield last year, which is how a relatively low-key addition of Jacquizz Rodgers in September ended up giving the team its leading rusher in 2016. Doug Martin missed half of the season with injuries and topped out at 421 yards; he also started a league suspension in Week 17 that will bleed into the first three games of 2017.
