How the league works

2K Sim Leagueis a persistent, career-driven basketball league layered on top of NBA 2K26. You create and own exactly one player, develop it over a full career, join a team run by a human manager, and follow automated, streamed games. This page explains the whole system — the player model, the economy, teams, and the season clock — so you know what you're signing up for.

One player, one career

Everyone controls a single player — not a roster, not a franchise. That player is yours from creation through retirement. You choose a position and an optional specialization, then roll a build. When your career ends the player retires as a permanent Legend and you can start a brand-new career from scratch.

Because you live with one player for a whole career, every decision matters: the attributes you buy, the badges you chase, and the identity you build toward.

Physicals are permanent; skills are earned

At creation your physical attributes — height, weight, wingspan, and raw athleticism (speed, agility, strength, vertical) — are rolled at random within realistic ranges for your position. These are permanent. They can never be upgraded or re-rolled once creation is finalized, exactly like being born with a certain frame.

Everything else — your skill attributes (shooting, finishing, playmaking, defense, rebounding) and your badges — is earned and upgraded over your career by spending currency. The attribute and badge catalog mirrors NBA 2K26 exactly; nothing is invented.

Notably, there is no fatigue, stamina, or conditioning systemanywhere in this league. It simply doesn't exist here.

Three currencies that never mix

The economy runs on three separate currencies, and none of them is convertible into another:

  • Credits — earned by playing, and spent on attribute and badge upgrades. This is your personal development currency.
  • Franchise Funds — a team currency held by managers, spent on roster actions like signing and keeping players under a salary cap. Franchise Funds never buy player power.
  • XP — earned through community quests, and spent on the finer identity of your player: tendencies, signature animations, and hot zones.

Keeping the currencies separate keeps development, team-building, and personalization from cannibalizing each other.

Teams, contracts & the cap

Human managers run teams. A manager signs free agents to weekly contracts, subject to a salary cap — the sum of a team's active contracts can't exceed its cap. Players collect their weekly salary in Credits, so landing a good contract directly fuels your development. Managers also set a coaching profile and each player's touches, shaping how the team plays.

The weekly clock & seasons

The league runs on a weekly clock. Almost everything — games, contract windows, careers, and seasons — is measured in weeks rather than real-time dates. Each season is divided into phases (offseason, preseason, the regular season, and the playoffs), and the current phase is derived from the advancing week.

Standings come from played games, box scores feed per-player and per-team stats, and a weighted draft lottery gives struggling teams better odds at incoming talent.

Careers, aging & Legends

A career runs for a set number of weeks in the main league. As it winds down, age catches up: athletic ratings gradually regress toward a floor, while your earned skills, badges, and identity stay intact. At the end, your player retires as a Legend — a permanent, read-only record of everything you built — and you're free to begin a new career.
