Positionless basketball refers to the idea that the old, traditional five positions (PG, SG, SF, PF, C) are no longer the best way to describe how players actually play on the floor. There are centers who bring up the ball, point guards who aren't specializing in playmaking, lineups with an average height of 6'8", the landscape of the modern NBA is changing past positions. Instead of relying on a single position label, SimulNBA groups players by Role based on what they actually do in games.
The five traditional positions (PG, SG, SF, PF, C) describe where a player used to line up, not what they actually do on the floor. A stretch four who shoots threes and a bruising post-up four have almost nothing in common, even though a scoreboard would list them both as "PF."
A Role groups players by what they actually do on the floor, so it regularly pulls together players from completely different traditional positions. Here are three roles, each shared by a guard and a big.
The flip side is just as common: two players can share a traditional position and play completely different roles. Here's each player's play-type mix, pulled straight from their Player Card. Click a chart to see the full breakdown.
Not quite. Teams still need size, spacing, and rebounding on the floor, positionless basketball just means those needs aren't tied to a rigid PG/SG/SF/PF/C label anymore. A team can meet them with a 6'4" guard who rebounds well instead of a traditional big.
Rule changes and the rise of three-point shooting rewarded lineups that could switch defensively and space the floor offensively, skills that don't map cleanly onto the old five labels. Teams found it more useful to build around specific skill combinations than around filling five fixed slots.
By Role, a grouping based on what a player actually does in games (shot profile, playmaking load, defensive assignment) rather than what position they're listed at. Two players can share a position and have completely different roles, or share a role from two different positions.
