UFC president Dana White is not a man who gives up easily. A hard push late last year to book a superfight between his Middleweight champ Anderson Silva and Welterweight champ Georges St. Pierre, foundered when GSP expressed no interest in moving up. Never-say-die Dana is still pushing the fight now and again when he gets a chance.
Here's what he told the press in London last week: "Anderson would go to [170 pounds], too. Yeah, he said he'd do it. He says he can make  easy. It's insane."
This is a pretty strong contrast with comments from Silva's conditioning coach:
It would be a crime for Anderson to try and fight at 77kg (170 lbs). He could maybe make the weight but the physical loss that he would suffer would be too much.
I'll leave it to you, the Bloody Elbow reader, to diagnose the insanity here.
