"however if they fought in the street or in mma rules i would bet on Sherk"
I disagree, I think that floyd would take Sherk in a street fight. Mainly because Floyd always has a gang of guys with him who are known for jumping people.
"I agree about Flyd being 1000 better talent than Sherk. Sherk has very little talent, and he is an example of the problems with UFC format. The cage allows for lameos like him to get owned and still pick up the "W" like when Diaz clowned him for 3 rounds."
"And yet in a boxing match, Sherk wouldn't last 100 seconds with Floyd. Whats your point?"
I don't recall Sherk bragging about how he would own any boxer in a boxing match. The point is that Mayweather is a clown for claiming that he would defeat a champion-caliber MMA fighter in a UFC match, and a fool if he actually believes his own nonsense.
