You guys are losing sight of the original point. Most people would see the 140lb stat and think of a little guy that they wouldn't have to worry about. But a professional fighter at pretty much any weight will destroy a bigger guy who is not a pro fighter.

Kimbo showed he is the sham all fight-enthusiasts claimed he was. Seth Petruzelli is a 3rd-tier heavyweight (who I think dropped to 205 for his original fight, so he fought Kimbo while underweight) and he dropped Kimbo with a short punch. Even Lesnar is a more legit fighter than Kimbo. I'd have loved to see Lesnar vs Kimbo, the battle of the two possible shams.

Lesnar has somewhat proven he is not completely incompetent though, since he has wrestling (not pro wrestling in this case) skill. I'd like to see how he takes a punch though.
