LOL if only Unforgiven knew that Charr would finally become a champion, that 40 yo Povetkin and Old Man Pulev and the ghost of Chisora would be top fighters and that the HW champion would be a refugee from a fat farm after Wlad retired ... he may have enjoyed the strong and healthy era he was in
Klitschko is far worse matchup for Langford than Wilder. It's very unlikely that he would beat him. Of course, with someone as powerful as Langford there is always a puncher's chance but I wouldn't bet on it. Wladimir was extremely good at beating shorter fighters. Langford could give him some problems with his short body early on, but he wouldn't sustain the whole fight of very strong clinching, powerful jab and killer right hand. At least that's my opinion. You can't tame away Langford chances against anyone, but Wlad is one of the worst matchups I can think of for him.
For the clueless old senile boxing fans who picked Sam Langford. Maybe it is time to check yourself into a old peoples home. The 6'5 240 pound modern sized, modern skilled Wladimir Klitschko would of knocked out the primitive skilled 170 pound Langford in less than 30 seconds.
