The Raiders are bringing back RB Doug Martin, sources tell me and @wyche89. Martin ran got 723 yards with Oakland last year. Rejoins the team following the loss of Isaiah Crowell.
Related players: Josh Jacobs, Jalen Richard, DeAndre Washington, Chris Warren
Martin will likely serve as the backup to Josh Jacobs. Isaiah Crowell was more of a threat to Jacobs' workload than Martin is, so Jacobs is in line for 250+ touches as the Raiders' lead back.
