With the 2025 Fantasy football playoffs starting for many, who you slot into your Week 15 Fantasy football lineups is of utmost importance. Every Fantasy start-sit decision deserves a little more time and consideration, and observing how an opposing defense has performed is Fantasy football advice everyone should heed.

He is coming off, by far, the best game of his pro career with three passing touchdowns and no turnovers in Sunday's win over Washington.

Now the model, which simulates every NFL game 10,000 times, has revealed its latest Week 15 Fantasy football rankings.

One player the model is high on this week: Commanders running back Chris Rodriguez Jr., despite him being the RB50 in standard leagues and being started in just 35% of leagues this week.
