Debates about who the greatest of all time in any sport remains an unending conversation. While it is impossible to truly determine who the best is, it's still fun to speculate about possible matchups and the potential outcomes across the sports landscape. For boxing fans, seeing Floyd Mayweather matched up against some of the past greats, like a Sugar Ray Leonard for instance, would be an indicator if he's truly TBE (The Best Ever). 

Sugar Ray Leonard recently appeared on Undisputed with Skip Bayless and Shannon Sharpe where he talked about the state of boxing. During the conversation, Leonard was asked whether he believes he could've beat Floyd Mayweather in his prime and he unsurprisingly answered "absolutely." 

But do you think Sugar Ray Leonard could've gotten past Floyd Mayweather and if not, what boxer from the past could hand Mayweather an "L."
