Every offseason, we use Basketball Reference's previous season's play-by-play data to see how often a player played at each position. If a player spent more than 20% at a position, they get that eligibility here.

If you're the commissioner of a formal keeper league, you can opt to grandfather positions for players still on rosters, so that these do not change (for the better or for the worse).

If you're starting new, this is what's new in 2024-25.
