Had Vitali never QUIT against Byrd, and been wrongly treated for his back trouble, he'd have a MUCH better resume, and likely have Toney, Rahman, Ruiz, Holyfield, and Valuev on his resume. All by KO of course.
Add Haye to that, and if that don't make him a top 10 ATG, I don't know what does.
But, as it stands, we can only rank him 10-20 or just outside those positions. Unlike Wlad, he's lacking 4-8 big fights in his prime, and he's got MAYBE another 2 in him if he decides to fight on.
I sure wish Mitchell woulda won that fight last w/e. He and Haye might have cemented Vitali inside the top 10 for me.
