Mismatch. Valuev all day long. I'm not sure what's worse, that these hopeless mismatch threads keep getting made or that there are always a few people plumping for a guy that would be out of his depth... Picking Joyce over Wlad or Delboy over Valuev, etc, madness.
Chisora is a guy that doesn't beat about the bush, he uses his physicality and attacks head on. So life is going to suck mightily when he tries to run through Valuev, as close to an actual giant in combat sports as you're gonna get. He's the wrong guy to be in-your-face against, and while he was as slow as molasses, he was insanely durable and still managed to land a lot of shots on his opponents. It's gonna be a long night for Chisora.
