The only klitschko leaving a mark in the the atg rankings is wlad. Sadly (because I believe vitali does better h2h) vitali will not. Infact vitali will be most famous for losing to lewis. Wlad will probably be remembered alongside holmes when all is said and done. A solid number ten. Vitali probably won't break the top 30
Well since I'm a fan of Vitali I'd prefer him to retire with his record intact. Then the WBC can have the 2 highest ranked guys fight for the belt and Wlad can unify against the winner. That would be a perfect way toward unification.
