The Klitschkos are great the problem is they have no opponents to bring it out Vitali brought it out vs Lewis but lost in a great effort that many still argue over today He got cut short by injury The Klitschkos have been hampered because they are fighting in a transitional era Lewis had Holyfield, Tyson, Foreman, Moorer, Mercer, Morrisson, left over 80's holders, Bowe, Golota floating around at his time Ali had Liston, Patterson, Quarry, Foreman, Shavers, Norton, Young, Lyle at points of his day Marciano had Charles, Walcott Louis and Moore Tyson had Holmes Spinks Tubbs Dokes BoneCrusher Tucker floating around Wlad and Vitali were the start of a new age all of the Lewis era guys retired or are too ancient to take credit for Also at HWT there is no mobility its not like WW or MW or LHWT where you lose to the champ and just move up to get credentials you need to beat top 10 guys, holders past present and future and future hall of famers Now Wlad fights top 10 guys even top 5 usually, Vitali fought Arreola and Gomez (i think) and Peter when they were top 10 Dont know if we count the WBO if we do Wlad beat Byrd, Mercer, Botha (did he hold a belt ever) Chagaev, Ibragimov, Peter 2X, Brewster, Rahman Vitali beat Hide, Sanders, Gomez, Peter, Norris, Briggs Hall of fame none id imagine Also who ever the brothers beat are done, theyll never have achievments they beat you take your 0 and then you never get a rematch so you cant get a belt they beat good opponents who probably could be belt holders thus criteria for the bros but the bros and Haye are holding the belts They start a new era they clean it out they cant get much credentials from guys who never will win titles they can clean out a new era of guys like Wilder Puleev, Ustinov, and so on
