Danny Green. This guy has made millions of dollar and never beaten a top 5 fighter in any weight class he has fought in.
Viktor Postol is a good example for an overarchiver imo. The guy is stiff, he is not strong, not fast, he doesn't punch hard. He doesn't really have much God-given talent for the sport. Yet he was a world champion, he beat a solid Matthysse and made some fighters like Garcia avoid him.
Yeah 9 rounds for Floyd is nuts. Maidana clearly won 4 or 5 of the first 5 rounds I remember sitting home with my brother watching it thinking we may see him lose he was cut could barely see, got mauled in round 1 his corner looked in a panic and then suddenly he came alive
