Who Should I Start? Brian Robinson Jr. or James Cook

Monday, December 15, 10:20 PM

Across 14 games this season, San Francisco 49ers running back Brian Robinson Jr. has recorded 349 rushing yards and two touchdowns on 81 carries. The 26-year-old has spent the entirety of the 2025 season in a backup role behind star 49ers running back Christian McCaffrey. Robinson Jr. has yet to record double-digit carries in a game in 2025 and has just seven receptions on the season, so his standalone fantasy value is limited. However, if McCaffrey were to suffer an injury, Robinson Jr. would immediately become a viable starting fantasy running back. He's proven he can succeed in a lead-back role in the past, racking up 799 rushing yards and eight touchdowns on 187 carries across 14 games with the Washington Commanders in 2024. In fantasy leagues with 12 or more teams, Robinson Jr. is worth rostering just in case McCaffrey goes down.

Buffalo Bills running back James Cook put up a dominant performance in his team's critical Week 15 win over its division rival, the New England Patriots, on Sunday. Cook recorded 22 carries for 107 yards and two touchdowns, and two receptions for four yards and a score. The 26-year-old has now racked up 1,686 yards from scrimmage and 12 touchdowns on 302 touches across 14 games this season. Cook has topped 100 scrimmage yards in five straight games and 11 out of 14 total contests in 2025. He also continues to dominate backfield touches in Buffalo, logging 22 of the team's 26 rushing attempts by running backs in Week 15. Cook profiles as a must-start fantasy running back heading into a Week 16 matchup against the Cleveland Browns.
