Heavyweights that achieved a lot since being brutally knocked out

Dillian Whyte was brutally KTFOed by Anthony Joshua and yet he came back in impressive fashion, winning 9 fights and beating some good or very good (Parker) opponents. Some of them with extremely brutal KO's (Browne, Chisora)

But who were other heavyweight that ahieved more after their brutal KO losses than before?

Hasim Rahman was knocked out cold and thrown out of the ring by Oleg Maskaev and yet he won titles twice, knocked out ATG Lennox Lewis, stopped Corrie Sanders and beat David Tua in rematch (officially it was a draw but everyone knows than Rahman won that fight).

Corrie Sanders was brutally knocked out by Nate Tubbs but won WBO title after that destroying future ATG Wladimir Klitschko.

But the best example of fighter coming back from brutal KTFO losses to ahieve more is Oleg Maskaev. His KO losses to McCall and Tua were really bad, but his KTFO losses to Kirk Johnson, Lance Whitaker and Corey Sanders were downright BRUTAL KTFO losses and he still won WBC title after them knocking out Hasim Rahman again in the rematch.

Can you name any other examples of heavyweights, who achieve much more after brutal KTFO losses than before them?

 

Yeah, but I wouldn't call his KO loss to McCall a "brutal KTFO". Rahman's KO was brutal indeed, but Lennox already had a great career before that fight.

 

Yes, definitely. But I was saying that he did have a great career before brutal KTFO loss to Rahman, and McCall loss while was realy bad, but not a brutal KO.
