If boxing were a nation, its capital these days would be the welterweight division. Among the 147-pounders are three or perhaps four of the premier pugilists in the world: Manny Pacquiao (51-3-2, 38 knockouts), Floyd Mayweather Jr. (40-0, 25 KOs), "Sugar" Shane Mosley (46-5, 39 KOs) and, on the cusp, Andre Berto (26-0, 20 KOs).
