Cant see all the images right now, but why no Rings, for instance?
98 LHW - Dan Henderson (Rings)
00 HW - Kiyoshi Tamura (Rings)
01 HW - Tsuyoshi Kosaka (Rings)
Based on my methodology, a top ten fighter is assigned to an organization based on which organization had the majority of their fights in a single year.
For example, Nogueira was a Rings fighter in 2000, but he wasn't in the top ten in January of that year, thus he wasn't listed. He was in the top ten in January of 2001, but he was a Pride fighter in that year (3 fights in Pride, 1 in Rings).
If I were to expand the rankings to include more than just the top ten, I wouldn't be surprised if Rings had a higher number in each year for the late 90s and early 00s, but to be honest that's more work than I wanted to put in this thread (expanding the list to say the top 15 would
add 90 additional fighters for me to assign to organizations).
See above; additionally, they had a lot more fighters in the lighter weight classes, which Pride and the UFC didn't put much time into until the tail end of Pride's run.
Do the other divisions though
No.
Youtube has some old RINGS fights but you have to keep in mind the scoring criteria is different than modern rules, sub attempts counted for way more than they currently do and top control didn't matter as much.
They also immediately stopped fights if someone got cut (see Emelianenko vs. Kohsaka).
