@Anut I love how you always are picking Wlad's opponents to win, and then as soon as they lose they are fat bums.
Undisputed means "there is no dispute", Wlad isn't undisputed at the moment thanks to his brother, just like Haye wasn't undisputed due to Wlolacyzk/Cunningham. In fact Buster Douglas was never "undisputed" champion thanks to that silly WBO belt. Hopkins and Taylor are the ONLY 2 undisputed champions of the 4 belt era...which is a bloody worrying thought. Though you could likely make an arguement for Hamed (who won the WBO, WBC and IBF titles and had beaten the WBA champion Vazquez) though was screwed by politics.
