I'm considering two factors when putting this together (1) workrate (2) everything else.
For me, as I've mentioned at greater length on more than one occasion, workrate is by far my most important consideration when evaluating a wrestler - I want to see athleticism or crispness or brutality or some combination thereof. Famous guys staring at each other regardless of crowd reaction is not as interesting to me as a high angle suplex.
But the list can't just be workrate, otherwise Katsuhiko Nakajima would rank ahead of Bruno Sammartino.
So the other category is everything else, some combination of titles earned or importance or overall recognition. My ballot for Meltzer's Wrestler of the Year Award is essentially this idea; my calculation rates workrate as solidly more important than would most, but some combination of actual in ring ability + other stuff is that award.
In the rankings, I offer some alternatives for each spot, probably through the first 25, maybe 50 - people who are similar, for some reason, but who didn't make this cut.
Is it a good list? Eh. Absent metrics I don't know how useful it is - but I hadn't done it before, so there you go. With that...
