Of all the recent challengers to Vladmir Klitschko's Heavyweight title (Yes, he's the Heavyweight Champ!), Philadelphia's Eddie Chambers has the best chance for an upset. Chambers is the best American heavyweight, and proved he has the blueprint on how to neutralize a 6'-7" European-style fighter, when he beat Alexander Dimintrenko last summer. It's a shame it's only available on the Internet - HBO passed on the bout. While U.S. fans have become bored with Klitschko-dominance, this will draw more than 50,000 in a soccer stadium in Dusseldorf, Germany. I expect Chambers to be competitive.
