Haye has mouth - and plenty of trousers
Monte Barrett was flat on his back before his opponent had even left his dressing room. David Haye was good, but he wasn't that good. Maybe Monte wanted to get acclimatised.
For it was a position the New Yorker would adopt frequently as the evening wore on - six times in all, if you include his ill-advised ring entrance.
Naseem Hamed liked to be lowered into the ring on a magic carpet. Barrett looked like he'd been blasted out of a cannon. After four and a half rounds of heavy shelling from Haye, he looked like he wanted to climb back in.
"I know I talk a lot of smack," said Haye following his demolition of Barrett at London's O2 Arena. "But I promised I'd deliver and I did."
Barrett, a seasoned pro who has been in with world champions Wladimir Klitschko, Hasim Rahman and Nikolay Valuev, as well as defeating a couple of much-hyped prospects, will not have seen the like of Haye before.
The former undisputed cruiserweight king was too quick, too slick and too powerful for his 37-year-old rival. Just as importantly, he showed he can withstand a heavyweight punch. Whether he can withstand a Klitschko punch, well that's a different matter.
Vitali Klitschko, the WBC heavyweight champion, was the man watching from ringside, but Haye's trainer Adam Booth made it abundantly clear at the post-fight presser that it was his younger brother Wladimir, who holds the IBF and WBO belts, that he'd prefer his charge to fight next year.
"Monte's got a better chin than Wladimir, so if David can nail him, he'll hit the floor," said Booth. Which is all very well, but what if Klitschko nails Haye first? But perhaps I'm missing the point...
Haye admitted he had abandoned the pre-fight game-plan after two rounds against Barrett and been drawn into a slugging match. That might not be the best way to go against Wladimir, who also floored Barrett five times when they met in 2000 and who has 45 knockouts from 54 fights.
"Monte buzzed me a couple of times with good shots and once someone buzzes me, that's when I plant my feet and start swinging," said the 28-year-old Haye.
"In the cruiserweights, I could do what I wanted because I could take the shots that came back. But you take a shot at heavyweight and you're on the floor straightaway. It's a learning process. I'm nowhere near the finished article."
Then why the rush? Booth said Haye would have a tune-up in the spring if neither Klitschko is ready before then, but even Evander Holyfield (remember him? He was great once) had six fights at heavyweight before going for the big one.
Ah, but there I go missing the point again. In Haye's world, it's kill or be killed. It's all part of the package, what makes him so endearing to some, so unappealing to others. When asked which Klitschko he'd like to fight, Haye answered: "Flip a coin, I don't care".
Personally, I love it.
"I don't feel I have to be the finished article to win a heavyweight title," he added. "I want to beat both Klitschko brothers on the way to being the finished article."
Haye and Booth are acutely aware the Klitschko brothers need Haye as much as Haye wants them. "They're interested because there are no other exciting challengers for them," said Haye. And he's right.
"They want to secure their legacy and who better to fight than the undisputed cruiserweight champion who's stepping up with this big knockout ratio?"
And what will make a fight with Haye even more attractive to the Klitschkos is the interest of American television networks.
Haye may not be one of their own, but he showed on Saturday that he's a million miles away from the lumbering East Europeans that have dominated the heavyweight scene for far too long. And that will be good enough for the network bosses.
As Booth pointed out: "To Americans, heavyweight boxing's not supposed to be about points decisions, it's supposed to be about knockouts. Forget game-plans from now on, I think we'll just go out swinging." He was joking. I think.
Haye's stay in the heavyweight ranks promises to be a brief one. Who knows if it will be a glorious one. But if Saturday night is anything to go by, it will be a tremendously exciting one.
The O2 Arena was flogging two tickets for the price of one in the lead-up to his fight against Barrett. I can safely say that won't happen again for the remainder of Haye's career.
"We should enjoy him while he's here," said Booth. "Because when he's gone, there'll be no heavyweights around to entertain us."
The Bermondsey Boy is that rare thing in modern boxing - a big man with moves, a big man with speed and a big man whose trousers are as big as his very big mouth. They don't come along very often. The British public should clamber aboard. It's going to be a rollicking ride.
