Top Legacy Fighters in Combat Sports. I think the following: 1. Floyd Mayweather - no question. record speaks for itself 2. Jon Jones - undefeated technically 3. GSP - finished on a high note. he came back to beat the 185 pound champion 4. Khabib - career not over, but on the right track to main the undefeated record 5. Gabi Garcia - lol. beating grandmas. sure why not 6. Amanda Nunes/Cyborg, etc. 7. Daniel Cormier - other than Jon Jones, he has achieved a lot and also became the Heavyweight champion I think Fedor and Anderson Silva ruined their legacy a little bit by staying longer (similar to Mike Tyson). Please mention fighters that I've missed.
