In the final week or so left before Floyd Mayweather faces Saul Alvarez, expect to hear the pound-for-pound king and his many fans repeat a common refrain: "Men lie and women lie, but numbers don't lie."
It's got a catchy ring to it, but that doesn't mean it isn't hooey. Of course, numbers don't lie. But like any facts, they can be employed to create misleading arguments.
Just the same, Mayweather's 44-fight winning streak is a major accomplishment in the sport's history.
Other impressive winning streaks didn't quite make the cut for me. Joe Calzaghe's 46-0 record will get him into the Hall of Fame. But his quality of opposition doesn't meet the level of those I've rated ahead of him here.
Ricardo Lopez, similarly, just misses the top 10. He was a dazzling fighter, and you can't argue with 51-0-1. But the quality of opposition at 105 and 108 pounds just isn't the same as it is in the higher weight classes.
