Also, which fighters have the most impressive records when it comes to combined opponent’s win/loss ratio? Interested to see if there are any fighters who set out to fight only undefeated fighters from the start and which fighters overall had the toughest matchmaking.
Wlad took a lot of zeros: peter, pulev, ibragimov, chagaev, poverktin, pulev, Brock, Jennings, pianetta Usyk took some zeros auf champions: glowacki, breidies, gassiev and fury + contenders like hunter Lewis took the zero of grant
Some Thai probably has a similar record due to lack of record keeping. Sirimongkol Singwancha has 22 "undefeated" opponents on his resume, 20 of them being debutants.
That's an under played point imo. I'm sure the same is true for more modern fighter in nations with less infrastructure like this Thai example but as time goes on and more and more records or proof of fights and results is found these debutants sometimes get updates with complete records. Meaning not every debut on Boxrec is a debut. Sometimes it's just the first fight we have record of. If I could award points for great posts I would. Very good point bud.
