Who Should I Start? Matthew Stafford or Marcus Mariota

Saturday, December 13, 8:57 AM

Los Angeles Rams quarterback Matthew Stafford meets his old team, the Detroit Lions, for a revenge game on Sunday in Week 15. Stafford is having the best season of his storied career, completing exactly one-third of his pass attempts for 3,354 yards, 35 touchdowns, and just four interceptions. He has supported fantasy-relevant roles for a wide variety of Rams skill players, including Puka Nacua, Davante Adams, and Colby Parkinson, as well as running backs Kyren Williams and Blake Corum. Stafford's strong campaign should continue this week. While he was already quite matchup-proof, he should find plenty of success against the Lions, who have allowed the fifth-most passing touchdowns and sixth-most fantasy points to opposing quarterbacks in 2025. He ranks as the overall QB2 in this week's RotoBaller fantasy rankings and should be started in all leagues.

Washington Commanders quarterback Marcus Mariota will remain under center for the rest of the regular season after the team officially shut down Jayden Daniels (elbow) for the final three games. Mariota has started seven games this season and has posted top-10 fantasy value in three of them. The 32-year-old had a less-than-ideal outing versus the New York Giants on Sunday, throwing for 211 yards with a touchdown while rushing the ball 10 times for 43 yards on the ground. He doesn't have the strongest arm, but his dual-threat ability gives Mariota streaming appeal the rest of the way. He'll head into a challenging matchup against the Philadelphia Eagles in Week 16. Mariota should still offer superflex value as a QB2 in a difficult home matchup.
