Agreed, we all remember what happend to Awkinwande in the 10th round after he got a little tired, McCall landed that one big right hand and put him to sleep. Haye's team knows Rahman easier prey right now, and after seeing Rahmans last couple fights on Versus, I have no doubt that Haye will knock him out. Tarus "The Bull" Sykes almost knocked him out last year and took him the distance, the same guy Sam Peter layed out and punched his head off the ropes as he was going down, and made him look like nothing finishing him off in the early rounds.
the biggest question i have about haye is his stamina and ring intelligence. there will be situations where he cannot knock someone out. will he be smart and just box or fight stupid and continue throwing hayemakers looking for the KO? im not sure he understands his limitations all that well. Rahman, Tua, or Mccall aren't what id call "live" opponents but Mccall and Tua have big chins. Get the fight late and test the Hayemakers stamina. Tua does have that one punch ko power but he has problems letting go now.
I guess if he continues to throw hayemakers, that means he's not yet convinced that he cannont knock them out.
Tua is a bigger puncher than Haye and has a VASTLY better chin. Haye has a speed advantage, but Tua will catch him at some point. Tua by mid-rounds massacre.
