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

Across 16 games this season, San Francisco 49ers running back Brian Robinson Jr. has recorded 90 carries for 391 yards and two touchdowns. The 26-year-old has spent the entirety of 2025 in a secondary role behind star 49ers running back Christian McCaffrey, who leads the NFL with 399 touches heading into the team's Week 18 matchup against the Seattle Seahawks. Robinson Jr. has been fairly efficient when given the opportunity so far this season, averaging 4.3 yards per carry. He's also proven to be a productive lead back at certain points in his career, recording 2,720 rushing yards and 22 total touchdowns across 57 career NFL games. However, his production upside in San Francisco is firmly capped as long as McCaffrey remains healthy. Robinson Jr. should not be on fantasy radars heading into Week 18.

Buffalo Bills running back James Cook took two carries for 15 yards in an abbreviated appearance in the team's Week 18 win over the Jets. It was enough to keep distance between him and a surging Derrick Henry, with Cook ultimately securing his first regular-season rushing crown with 1,621 yards. Heading into the postseason, he should be viewed as one of the highest upside running backs in fantasy playoff leagues. Buffalo currently holds the fourth-highest Super Bowl odds in a wide-open AFC and is a slight road favorite over a 13-4 Jacksonville team that has been a headache for fantasy running backs throughout most of the season. Despite the tough matchup, Cook is RotoBaller's RB2 for the week, and he could be in line for a massive postseason if Buffalo can advance.
