Conferences
Ranked by a top-weighted average of member ratings: each next-best team in a conference counts 10% less than the one above it. That measures quality at the top while still counting depth, and unlike a plain mean it does not punish an eighteen-team league for its tail. The plain mean is shown beside it.

Not conferences
Fewer than 4 teams, so these are listed rather than ranked. Independents are the absence of a conference, and a two-team average of them is not a statement about any league.
