Montgomery signed with the Lions as a de facto Jamaal Williams replacement and will team up with rookie Jahmyr Gibbs to form a potentially-elite RB duo. During four seasons in Chicago, Montgomery never finished a season lower than 20th in touches, 21st in yards or 24th in fantasy points among RBs. Even with Gibbs in the mix, he has a good chance to keep that streak going, especially in a fantasy-friendly role that allowed Williams a league-high 17 TDs and 28 carries inside the opponent's 5-yard line last season. Montgomery (14th among RBs in targets since 2019) is a more accomplished receiver than Williams, so there's a lot to like in a Detroit offense that led the NFL with 501 RB fantasy points in 2022. Target Montgomery as a flex option.
