Who Should I Start? Jordan Mason or James Cook

Wednesday, December 24, 3:27 PM

Minnesota Vikings running back Jordan Mason (ankle) has been ruled out for the Christmas Day game on Thursday versus the division-rival Detroit Lions after missing practice from Monday through Wednesday, per the team. Mason was always viewed as a long shot to play on a short week after injuring his ankle in the Week 16 win over the New York Giants on Sunday. The Vikings have nothing left to play for in 2025, so they were not going to push Mason to play. With the 26-year-old on the sidelines on Thursday, Aaron Jones Sr. should be in line for more backfield touches against the Lions. However, his fantasy upside will be tempered with inexperienced backup quarterback Max Brosmer set to start in place of the injured J.J. McCarthy (hand). Jones should be considered more of a touchdown-dependent, high-end RB3/flex for the matchup against the Lions.

Buffalo Bills running back James Cook was dominant in Week 16's win over the Cleveland Browns, totaling 134 scrimmage yards and two touchdowns on just 17 touches. Cook has ascended once again in the 2025 season, jumping from 79.2 scrimmage yards per game in 2024 to 121.3 this season. He currently leads the NFL in rushing yards and ranks RB6 in PPR formats. The Bills host the Philadelphia Eagles in Week 17, who have allowed the eighth-most fantasy points to running backs this season. While star defensive tackle Jalen Carter will be active this week for the Eagles, Cook and the Bills are running the ball with ease, so fantasy managers should expect more dominance from the fourth-year back.
