Bill Russell vs Shaquille O'Neal: who's the GOAT?

How the ranking works. Every head-to-head vote is a result, like a game. The standings use a Bradley–Terry model, the same idea behind chess ratings: beating a highly rated legend counts for more than beating a long shot. Ratings are shown on a chess-style scale centred on 1500.

One vote per matchup per person. If you see a pairing again in another session your new answer replaces the old one, so nobody can stuff the ballot by repeating a matchup.
