Austin was an early KO, Brock was a little later & Thompson was later than that. All of them have better chins than Haye.
I'd guess it will last 3 too, but I'm expecting the Haye camp to pull something goofy, like quitting on his stool feigning injury, or claiming that Dr K did something illegal, and that's because Haye has virtually zero chance of winning. What's he going to do, try the running away all night with an occasional potshot strategy he tried with Valuev? Well, that's not going to work here. It's a ridiculous mismatch. They only thing competative about Haye is his big mouth.
If Wlad comes out guns a blazing for Haye, he is a ****ing moron and deserves to be knocked out. He will take his time with Haye and take him out late, like he always does, or Haye will blast him in the first 3. This method is much better used for a fighter like Vitali Klitschko, who has done this and has the chin to hold up to a brawl with Haye. The only problem is his age. If Wladimir tries it he throws out all of his advantages just because of bad blood, he's going to get hurt because Haye wants this to happen, he's playing into his hands. I genuinely believe Wlad is not that stupid and if he tried it even for the first round, Emanuel Steward would be so ****ing pissed Wlad wouldn't bother to try it again.
If he couldn't KO Chambers in 3 how's he going to KO Haye in 3? Unless the bad blood will spark a fire under his ass to go for it. Nevertheless, betting on Wlad would be the smart thing to do.
The first time Haye is on the recieving end of one of those right hands, like the one that caused Brock to go limp, will be interesting. LOL
