Which boxer in their prime would never lose to another fighter?

[Robbie Barrett]

During that time he fought two great inside fighters (Haye and Chagaev) they couldn't get on the inside, I don't see any other fighter getting on the inside, even the very strong Povetkin couldn't get on the inside of a past prime Wlad

Did you just say Haye's a great inside fighter?

SRR. Willie Pep. ODLH. Floyd Jr. Tyson Fury. Locche. Salvador Sanchez. Jack Johnson. Aaron Pryor.

Mike Tyson 1986 to 1989

Above and RJJ, they were invincible in their prime

[Simurgh]

Gennady right now

[betmen]

nobody say mayweather.

he already proven that he's unbeaten prime or past prime

Prime Lewis.

He refused to lose. The simple question is not lose to another fighter this isn't a p4p list this is any fighter regardless of their size versus another at his actual size. So that's 5'8 147 Floyd vs 6'5 240 Lewis. Lewis by murder.

Can't say Mayweather because in his prime he barely squeaked past an ancient ODLH...

[NaijaD]

Had this exact look when I read that.
