Klitschko retires

[Skybird]

He started "weak", but then showed that he can improve. And he did - fundamentally. That is an accomplishment. He has beaten several world champions during his reign. He fought against all big names of his era. It is sometimes said he boxed during a time when boxing opponents generally were weak and especially US boxing was/is in a sad state, but his birthday is not his mistake and we will never know how he would have done with opponents from other times that their fans claim to have been greater. That all is just hear-say. By the end of the day, you look at the numbers and stats of the sport's scoring board - and then you have to realise that you deal with a boxer whose scores say he is one of the five or six best boxers in history.
