I know people are looking for a formula to beat floyd...this has been going on for about 10 years now. They said only a pressure fighter could beat him. He proved that theory wrong. Then they said a good boxer with fast hands would beat him...he proved that wrong by beating shane and judah. They said a guy with the right mix of boxing and slugging could do it. so there was cotto and guerrero. At this point it looks like we're going full circle again. They're saying a boxer with fast hands again. That's khan. After him they'll say a guy who can box AND slug. That's garcia. And after him they'll say a guy who can put pressure on him...that's thurman. then it will be 50-0 and game over and we'll all go home drink some warm milk and go to bed.
There are several styles to beat Mayweather but look at the quality of opponents you mentioned. Come on man.
