Seattle Seahawks (vs. IND)
Welcome to the NFL, Riley Leonard! For your first career start, you get to go into Seattle and face one of the three best defenses in the league. Good luck!
The Seahawks have been one of the best picks in fantasy at any position. Defensive scoring is different from platform to platform, but they’ve essentially given fantasy managers a useful game all but three times this season. Against the Cardinals and Vikings, they were matchup winners.
Now, the No. 1 defense in fantasy gets a home date against a rookie Day 3 quarterback making his first career start. That’s all you need to know.
Chicago Bears (vs. CLE)
Shedeur Sanders probably solidified his status as the Browns’ starting quarterback for the rest of the season. He now has four more games to prove he deserves to enter 2026 as the favorite to be the Week 1 starter.
As well as Sanders played last week, he is still a fifth-round rookie. And it’s not like there weren’t errors. Sanders is far from a complete player, but he was able to light up a very bad Titans defense. Things will not go as well this week.
The Browns are still allowing the fourth-most fantasy points per game to opposing defenses. Chicago in December is cold and a very difficult place to play. The Bears are coming off a tough divisional loss to the Packers and need this game for their playoff push.
Sanders has thrown an interception in three of his four appearances. He’s also taken eight sacks.
The Bears should force the Browns into negative game script, which creates more opportunities for sacks and turnovers. They are a strong streaming option in Week 15.
Jacksonville Jaguars DEF (vs. NYJ)
The Jacksonville Jaguars’ defense has quietly become one of the most reliable fantasy units of the season, entering Week 15 ranked fourth overall with an 8.3 point average through 14 games.
Their recent form is even more impressive, with four top-nine finishes in their last five outings as their opportunistic style of play has repeatedly caused problems for opponents. They bring a stable floor and a real shot at another top-tier defensive score this week.
The last three defenses to face the Jets all recorded top-10 fantasy weeks, with two finishing in the top five.
San Francisco 49ers DEF (vs. TEN)
San Francisco’s defense is regaining form at the right time, stacking three straight top 12 finishes before their Week 12 bye as they found a groove under Robert Saleh. The Titans’ offense has struggled to generate consistent yardage, let alone sustained scoring drives, which places the 49ers in a strong position to deliver another positive performance.
Miami Dolphins DEF (at PIT)
Miami’s defense carries significant momentum into Week 15 on the back of four straight top-eight fantasy finishes, with multiple turnovers in every game during that run. The Steelers have committed nine offensive turnovers in five non-divisional games since Week 5, compared to only two in divisional play, making Miami a solid bet this week.
