Fairly confident in the All & MMA rankings at this current time but definitely huge gaps for KT & TWGC in terms of missing fighters which fit the criteria. As always if there is any fighter which fits let me know and I'll add them into the rankings.
Down the line will potentially do a Finisher Legacy Undefeated Ranking thread but for now that would be too difficult to have an accurate data set for especially outside of MMA.
Tomorrow/ later today will have a deeper look into KT and TWGC but again those rankings are very incomplete so any additions will be hugely appreciated.
Check out:
for the legacy editions of undefeated fighter rankings throughout MMAT history, also as it is harder to track (especially KT and TWGC wise let me know anyone I missed there will be lots as I haven't had time to fully deep dive (and its difficult to find hidden gems))
TWGC (Minimum 10 Wins)
1.Giovanni De Rossi (387726), 12-0 - Active
2. Cesar Borges (406762), 11-0 - Active
3. Brady Swayde, 11-0 - Active
4. Harry Nile "Private Investigator" (395015), 10-0 - Active
(Annoyingly TWGC doesn't give the highest rank so the PFP will not be accurate to that of when they were undefeated so decided to leave out and it is not super relevant as most high ranked grappler have like 50+ matches)
