You're sweating. I know you are. It’s Week 13, and for most fantasy football managers, this is the literal "do or die" moment. You’re either clinching a playoff spot or you're about to spend your January looking at mock drafts for next year. It’s brutal. The bye weeks are hitting hard—with teams like the Browns, Packers, Titans, and Raiders taking a seat—and suddenly that "deep" roster of yours looks like a ghost town.
Fantasy football is basically a game of managing regret. You start the guy who’s been consistent all year, he duds, and the high-ceiling flyer on your bench goes for 30. We’ve all been there. But making the right sit em start em week 13 choices isn't just about chasing last week’s points. It’s about volume, defensive shells, and frankly, who’s actually healthy enough to run a vertical route right now.
Let's cut the fluff. You need wins.
Quarterbacks: Who to Trust When the Pressure is On
If you have Josh Allen or Jalen Hurts, you aren't reading this section. You're starting them. You’d start them if they were playing in a hurricane against the 1985 Bears. But for the rest of us mortals, the QB landscape is a minefield.
Brock Purdy is someone you’ve gotta keep in the lineup despite the occasional "game manager" labels people love to throw around. The 49ers' offense is a machine, and against a beatable secondary, Purdy’s efficiency is basically a cheat code. He doesn't need 40 pass attempts to give you 20 points because his YAC (yards after catch) monsters do the heavy lifting. On the flip side, I'm honestly nervous about Kirk Cousins this week. The veteran has looked a bit static in the pocket lately, and if the pass rush gets home early, he tends to crumble. It’s a risky play if you have a high-upside streamer on the wire.
Think about Bo Nix. Yeah, a rookie. But look at the rushing floor. In modern fantasy, a QB who can scramble for 40 yards and a touchdown is worth more than a pocket passer throwing for 300. Nix has shown he’s not afraid to tuck it and run when the first read isn't there. He’s a legitimate start em candidate for anyone dealing with the Jordan Love bye week.
Why Matchups Matter More Than Names
Sometimes we get blinded by the name on the back of the jersey. We remember the 2022 version of a player and ignore the 2025 reality. Defensive coordinators like Brian Flores in Minnesota are making life hell for experienced QBs by disguised blitzes. If your QB is facing a high-pressure rate defense, sit 'em. It doesn't matter how many Pro Bowls they have.

Running Backs: Volume is King, But Efficiency is Queen
Running back is a wasteland. Honestly, it’s depressing. If a guy gets 15 carries, he’s basically a RB1 in this economy.
Kyren Williams remains the heartbeat of the Rams, and you aren't sitting him. But let's talk about the "in-between" guys. Kareem Hunt has been defying the aging curve, absorbing an absurd amount of touches. While he isn't breaking off 50-yard runs, the goal-line work is gold. He’s a must-start simply because the Chiefs refuse to stop giving him the ball in the red zone.
The Breece Hall Situation
You’re starting Breece. You have to. But you’re doing it with a grimace. The Jets' offensive line has been… let’s be kind and say "porous." Hall is surviving on dump-off passes. If you're in a full PPR league, he’s fine. In standard? You’re praying for a breakaway that might not come against a disciplined front four.
Sit Em: The Trap Starts
Be very careful with Rachaad White. Bucky Irving is real. He’s faster, he’s hitting the holes harder, and he’s eating into the passing game work. White is becoming a touchdown-dependent RB3. If you have a guy like Chase Brown—who has fully taken over the Bengals' backfield—you play Brown every single time. Brown's explosive play rate is significantly higher, and Joe Burrow is keeping defenses honest, which opens up those light boxes for the run game.
- Joe Mixon: Hammer him. The volume is elite.
- Rhamondre Stevenson: Start, but expect a floor game. The Patriots' offense is an uphill climb.
- D'Andre Swift: Start him if the matchup is soft, sit if he’s facing a top-5 run defense. He needs space to be effective.
Wide Receivers: Navigating the Boom-Bust Cycle
This is where sit em start em week 13 gets truly chaotic. Receiver production is so tied to QB health and weather this time of year.
Nico Collins is back and looks like he never left. He’s the alpha. If he’s on your team, he’s in your lineup. Period. But what do we do with someone like George Pickens? He’s the definition of a "boom" player. He can catch a 60-yard bomb over three defenders, or he can disappear for three quarters because the Steelers decided to run the ball 40 times. This week, the matchup suggests a boom. The secondary he’s facing struggles with physical, contested-catch receivers.

The Rookie Surge
Keep an eye on Ladd McConkey. The kid is a route-running technician. Justin Herbert has clearly decided Ladd is his safety blanket. In any kind of PPR format, McConkey has moved from a "maybe" to a "must." He’s getting those high-value targets in the middle of the field that move the chains and pad your fantasy score.
On the "Sit" side of things, I’m fading Courtland Sutton if the weather in Denver looks nasty. He’s great, but the Broncos' passing attack is still a work in progress. If the wind is whipping, they’ll just lean on the run and short screens. You don’t want to be left holding a 3-catch, 34-yard stat line in a playoff push.
Tight Ends: The Great Disappointment
Is there anything more frustrating than the Tight End position? Probably not.
Travis Kelce is finally looking like Kelce again, which is a relief for everyone who spent a second-round pick on him. He’s a start. George Kittle is also a lock. But after those top three or four guys, you’re basically throwing darts at a board while blindfolded.
If you're desperate, look at Taysom Hill. Is he a tight end? No. Is he a quarterback? Sorta. Is he a fullback? Sometimes. But the Saints use him everywhere. In a week with heavy byes, Hill’s ability to vulture a rushing touchdown or throw a random 20-yard pass makes him a better start than a traditional TE who might get two targets all game.
Trey McBride is the real deal. If you have him, you’re likely winning your league. He’s basically a WR1 in a TE slot. He’s seeing a 25% target share, which is unheard of for a tight end not named Gronkowski or Kelce in their primes.

Defenses and Special Teams: Playing the Odds
Stream. Stream. Stream.
Don't be loyal to a defense. If the Houston Texans are playing a backup QB, you pick them up. If the Minnesota Vikings are at home, you play them. Brian Flores' defensive schemes are so confusing for young quarterbacks that they almost guarantee a couple of interceptions and a handful of sacks.
Avoid the Dallas Cowboys defense right now. They’ve been banged up, and the offense isn't staying on the field long enough to give them a break. They’re tired, they’re missing key pieces, and they’re giving up big plays. There are better options on the waiver wire. Look for teams playing against the Panthers or the Giants; it’s a boring strategy, but it works.
Actionable Advice for Your Week 13 Lineup
Winning at this stage requires a mix of cold-blooded logic and a little bit of "gut feeling." Here is how you should actually handle your roster over the next 48 hours:
- Check the Weather Reports: It’s late November/early December. A "good" matchup on paper can be ruined by a 20-mph crosswind. If the weather is bad, pivot to your RBs and high-volume slot receivers.
- The "Sunday Morning" Rule: Don't make panicked changes at 12:55 PM. Your Tuesday instincts are usually better than your pre-game jitters.
- Handcuff Your Stars: If you have a stud RB, make sure you own his backup. A Week 13 injury can end your season if you don't have the insurance policy ready to go.
- Ignore the "Projected" Points: ESPN and Yahoo projections are just guesses based on averages. They don't account for shadow coverage or a revenge game narrative. Trust the volume and the matchups over a computer-generated number.
The playoffs are right there. One or two correct sit em start em week 13 decisions are all that stand between you and a trophy. Look at the targets, look at the red zone touches, and don't be afraid to bench a "big name" for a guy who’s actually producing right now.
Check your injury reports one last time. Make sure your kickers aren't playing in a blizzard. Then, lock it in. You’ve done the work; now you just need the ball to bounce your way. Good luck.
