Liverkick.com reports that current Strikeforce MMA star and former K-1 World Prix Grand Champion Alistair Overeem says that he'd like to win the ongoing Strikeforce heavyweight tournament, and then move on to boxing to fight current WBC heavyweight titlist Vitali Klitschko.
Overeem is 6'5" and around 260 pounds of pure muscle (which has of course opened up rumors for a few years, as Overeem used to be a 205-pound fighter) who was born in England and grew up in the Netherlands, where he still resides. He's been a true force in MMA for the last few years, and his success in K-1 turned a lot of heads, too. Were he to actually try boxing, it would be a bold but I have to think respected venture, as it would be a man attempting to go to the top of a third combat sport, which would be unheard of, quite frankly.
Now obviously I don't think he could beat Vitali Klitschko in a boxing match, but then I didn't think Albert Sosnowski or Shannon Briggs could either, and those fights happened with zero intrigue or appeal beyond the normal Klitschko audience, so I guess what I'm saying is, hey, why not? What the hell? Everyone in heavyweight boxing is so far behind the Klitschko brothers that I couldn't blame Vitali for potentially entertaining the idea, as silly as it might sound to purists and even considering it's beyond unlikely to ever be a serious issue in the first place.
Klitschko, of course, came to boxing via kickboxing himself.
