The Boxing Writers Association of America (BWAA) decided to start publishing their own poll-based P4P rankings last August. This means we now have
5 major
or so-called “official” P4P lists; The Ring's, BoxRec's, ESPN's, the TBRB's & the BWAA's. The Ring's rankings have been viewed as
the authoritative list around the world for many, many years. The BWAA and TBRB (along with their own divisional rankings) are looking to change this. Some will naturally be less subjective than others due to their criteria, number & diversity of voting members on each panel, even down to how often they update their lists (the TBRB updates every week, on Tuesdays, which I like).
I found a Wikipedia page that will help keep track of all 5 major lists. Unfortunately, updates
could potentially take up to a week or more (Wiki contributors are volunteers after all). If you scroll to the bottom of the page it shows when it was last edited/updated.
