I still feel weird about Lesnar, hes a tremendous athlete and was a phenomenal collegiate wrestler, but he still did fake wrestling. Call it "predetermined" and say "the injuries are real!" all you want, its still just a giant Soap Opera and silly dramatics.
It really changed Lesnar for the worst; compare Sherk or Hughes (two strong wrestlers from the midwest) before, during and after a fight. And now look at what Lesnar does after he spent years in the WWE.
The last few seconds of his Heath Herring 'fight' really sealed it for me. He ran around the ring for the last few seconds cheering and then when Herring pounced, the horn sounded and the fight was over, the ref broke them up, and Lesnar pointed at his face and laughed. He clearly is still stuck on putting on a show and making a spectacle.
He will never be a true Mixed Martial Artist, hes like a Kimbo, and he is just capitalizing on his freakish size and fame.
