The General Manager Fantasy Football League is a dynasty contract league built on salary caps, multi-year contracts, franchise tags, holdouts, and deep roster strategy. It's the league that inspired JerryTrades — and it's the kind of league we think every serious fantasy group should try.
The GMFFL has been running for years among a close group of friends and family. It's not your typical redraft league. Every player carries a real contract — guaranteed or locked — with salary escalations, dead cap penalties, and trade implications that ripple across multiple seasons. You don't just set a lineup. You manage a franchise.
Running a league like this on MyFantasyLeague requires a massive amount of manual tracking — contracts, salary deferrals, dead cap calculations, holdout eligibility, franchise tag costs. That's exactly why JerryTrades was built. We needed a tool that could handle the complexity of a real GM contract league, and nothing else out there could.
These leagues are incredibly more strategic than basic fantasy football leagues, and we all love it. So we encourage you and your fantasy buddies to adopt leagues like this. The depth of decision-making — balancing win-now moves against long-term cap health, navigating holdouts, timing contract extensions — is what keeps every owner engaged year-round, not just during the season.
$300 cap. Every player has a guaranteed or locked contract with real financial consequences. Salary escalations, dead cap penalties, and cap compliance are year-round concerns.
Restructure contracts like a real NFL GM. Defer salary to free up cap now (at a cost), or advance future money to lock in value. Every dollar decision has trade-offs.
Tag expiring stars for one more year. Extend contracts before they expire. But each comes with rules — a player can only be franchised twice, and extensions are one-time-only.
Top performers demand new deals. If your star finishes in the top tier two years running, he'll hold out. Pay up, trade him, cut him, or stash him and wait it out for 7 games.
No lineup-setting anxiety. Your highest scorers automatically fill your starting spots each week. Focus on building the roster, not agonizing over Thursday night flex decisions.
Once a year, dice rolls simulate economic shifts, TV deals, labor negotiations, and league realignment — affecting salary caps and roster limits across the entire league.
