Anyone know if there are any undefeated heavyweights...

Carl Davis Drumond 6-0 6ko's Jake Goodnight 4-0 4ko's Johnnie White 5-0 5ko's Lightweight Edwin Valero 16-0 16ko's all in the first round. Jake Goodnight?!? HAHAHAHA!!!!

Ahh, Denis Boitsov with 9 wins and 9 ko's. Is he the highest currently? I believe he is the highest.

If you're looking for the bigger names (which I assume you are), off the top of my head, Rocky Marciano has the best KO % of any heavyweight with 49 wins and 43 KO's. Quick math and that's somewhere around 85-90%. Don't quote me on this, but I think it's right. Vit Klitsckko and FGeorge Foreman have 97% of their wins by KO.

Yeah, David "Nino" Rodriguez is a damn fine prospect who was 18-0 with 18 FIRST RD KOs and some of those later heavies were decent quality. He looks skilled too. Why he doesn't want to be a millionaire is beyond me. He's 6'5" in the 240s, looks like a model for GQ and Latinos would go nuts over him, hell everyone would. He's still young yet, but he just won a 4 rder in a nothing bout against novice journeyman type and going nowhere fast. He's blowing an opportunity of a lifetime, but he's young enough to make some hay still. His manager has got to be the dumbest guy on the planet and maybe Nino is too.

This is my homeboy, he was 18-0 with 18 ko's until his last fight. http://www.boxrec.com/boxer_display.php?boxer_id=047041

Hmmm. Maybe I wasn't clear. It seems everyone one of you misread my question. I was wondering if there were any undefeated heavyweights out there with all knockouts None of the guys you submitted are undefeated and have all their wins by KO.

with all K.O.'s? There's bound to be some out there, but I wonder who has the most? Denis Boitsov 9-0 (9KOS) http://www.boxrec.com/boxer_display.php?boxer_id=267630 Alex Povetkin 3-0 (3KOS) 2004 Olympic Gold Medalist http://www.boxrec.com/boxer_display.php?boxer_id=318081

Why can't you people read... He was asking if there are any undefeated HW's with all KO wins... and who has the longest streak

Donnell Holmes, Jean Francois Bergeron, Eddie Chambers, Nikolay Valuev.

Alexander Dimitrenko, Malik Scott, Ruslan Chagaev, Vladamir Virchis.

Leo Nolan, Roman Greenberg, Calvin Brock just to name a few.

We can't forget about Calvin Brock, he is undefeated. He can easily become a heavyweight champion in the future.
