Floyd Mayweather Jr. is in all likelihood in the homestretch of his remarkable career. He has the tough but raw Victor Ortiz scheduled for next month; the fight should not represent much more than a speed bump for Mayweather. There is at least some reason to hope that his long awaited showdown with Manny Pacquiao will be made for sometime in spring or summer 2012.
Win or lose against Pacquiao, it's tough to think of much beyond that to keep Mayweather in the game. He had some of his greatest moments at super featherweight, so it's hard to imagine him going all the way up to middleweight to take on somebody like Sergio Martinez.
Of late, Amir Khan has been lobbying for a fight with Mayweather. With Khan's star on the rise, the fight could be lucrative enough to interest Money. The other top man at junior welterweight, Timothy Bradley, might be a potential opponent as well.
With Mayweather's next fight on the horizon, and his retirement perhaps not much further off, I offer the following retrospective look at the man many rate the top pound-for-pound boxer of his era. These five fights are all among Mayweather's most historically significant efforts and showcased the Grand Rapids, Mich., native at his slick and punishing best.
