12The Gridiron Giants|Michael Smith2

I'm not going to tell anyone anything they don't already know about this team. I'm not going to calculate out if you would've won this game if you hadn't sold your team off already because that ship has sailed. There are still a couple decent trade targets here though with Lockett and Knox. At this point you just gotta keep putting points up to stay out of that last spot. It's a sad reality when your optimal lineup is getting outscored by half the league's bench players. The waiver wire is your only friend right now, but even then, you're operating with zero FAAB and a dream. Maybe next year you don't draft three quarterbacks in a one-QB league, but until then, enjoy the basement.

11The Underdogs|David Mitchell

The only thing more irresponsible than your gambling habits is how you're managing this team. You've had a couple opportunities to grab some assets for the draft next year but you've turned them down because your ego is too big. For a tank, you almost have no extra assets in next year's draft. Yikes. It's gotten to the point teams don't even want to talk to you because all you do is nickel and dime. When you inevitably complain about your bad luck in the group chat, just remember that luck has nothing to do with starting a defense on a bye week. It's truly a masterclass in how to alienate your fellow managers while simultaneously destroying a dynasty roster from the inside out.

10Monday Night Miracles|Chris Thompson1

Another week, another agonizingly close matchup that you managed to throw away in the fourth quarter of Monday Night Football. You've got all the pieces to be a contender, but your start/sit decisions are actively sabotaging this roster. Leaving 45 points on the bench while your flex puts up a goose egg is a tough look. The talent is there, but until you stop overthinking every Sunday morning, this team is destined for mediocrity. It's almost impressive how you consistently manage to snatch defeat from the jaws of victory. If there was an award for 'Most Points Left on the Bench', you'd be the undisputed champion. Do us all a favor and just auto-set your lineup from here on out.

1The Monstars|Sarah Jenkins1

Is anyone actually surprised? You mortgaged the future for win-now pieces and it's paying off in spades. The league is officially on notice. Your wide receiver room is downright terrifying, and barring any catastrophic injuries, this squad is looking like a lock for a deep playoff run. Just don't get too comfortable. The number one spot is still up for grabs. You're averaging an absurd 140 points per game, making the rest of us look like we're playing in a junior varsity league. Your waiver wire pickups have been flawless, your trades have been borderline robberies, and frankly, it's getting a little annoying to watch you victory lap in the chat every Tuesday morning. But credit where it's due: this is a juggernaut.

... And 9 More Teams

This is just a sneak peek. Every single manager in your 10, 12, or 14-team league gets roasted every single week.

Built for Sleeper and ESPN leagues. Delivered every week of the season.

How it works

  1. 01

    Connect your league

    Link a Sleeper or ESPN league. Rosters, scores, standings, and transactions sync on their own from then on.

  2. 02

    Let managers weigh in

    Anyone in the league can drop a take during the week. Rivalry folds the trash talk into the analysis — or writes the whole thing itself.

  3. 03

    Get the newsletter

    Each week a finished power-ranking newsletter lands in every inbox: rankings, expected wins, trade grades, rivalry records.

For commissioners

  • One sync replaces the Sunday-night writing session.
  • Pick the voice — measured analyst or full-time instigator.
  • Set the send time once. It ships itself every week.
  • Only you need an account. Managers get an invite link.

For managers

  • Add your own write-up before the rankings go out.
  • See who actually won each trade, not who claimed to.
  • Lifetime head-to-head records surface when you face a rival.
  • Read it in your inbox, on the web, or printed.

Numbers worth arguing about

Everything is computed from your own league's rosters, scores, and transactions — not a generic template.

Expected wins

Every team's record is simulated against every schedule in the league, so the standings show who is good and who is lucky.

Trade grades

Waxxtracker scores each deal after the fact and keeps a running ledger of who is winning trades and who is quietly getting fleeced.

Rivalry history

Lifetime head-to-head records, streaks, and playoff meetings appear automatically whenever two managers line up against each other.
