What We Saw: Week 15 — Fantasy Football Week in Review, Highlights & Start/Sit Tips (2026)

Bold start: The final week of What We Saw arrives with a heartfelt thank-you—and a reminder that every reader, analyst, and editor shapes the story we tell about the game. This week’s column wraps up the 2025 season with appreciation for the people who make it possible, from the analysts who grind through 256 games across 15 weeks to the senior leadership behind the QB List team, and most of all, you, the reader. Your engagement turns analysis into something meaningful beyond box scores, and your support has kept this feature thriving through a marathon of a season. With that spirit in mind, we dive into Week 15 and the postgame pulse of fantasy football.

Postseason routes are in plain sight, and Week 15 delivered a tapestry of surprise injuries and standout performances. Trevor Lawrence of the Jacksonville Jaguars put together a career day that propelled fantasy managers toward secure wins alongside his teammate Travis Etienne. On the other end of the spectrum, 44-year-old Philip Rivers took the field for the Colts in years, nearly guiding them to a victory over the Seattle Seahawks. Below are several other standout moments from around the league in Week 15.

  • James Cook III and the Bills defeated the New England Patriots, clinching a vital AFC East win that has real playoff implications.
  • Trey McBride demonstrated why some analysts viewed him as a foundation piece for fantasy rosters, adding two more touchdowns to his season total.
  • Bo Nix delivered a 300-yard, four-touchdown performance as the Broncos endured a tense moment against the Green Bay Packers.

Our analysts watched every snap so you don’t have to. Here’s What We Saw!
