Greatest boxers of all time, pound for pound

Can you name the boxers who are ranked in the all-time top 50, either in BoxRec's algorithmic P4P ratings (as of February 2026), or in a "Definitive Ranking" released by Bleacher Report (published December 2025)?

"Primary weight classes" listed below are per BoxRec

I chose to draw from two different rankings here, because the Bleacher Report list reflects popular opinion more, but the BoxRec list reflects more esoteric research
