What a Floyd Mayweather loss would actually mean for his brand and the sport of boxing

It seems near impossible, but what exactly are the ramifications for Mayweather falling against social media star Logan Paul?

It's a question that's hard to put into the proper context, mostly because the offshore betting odds are so wide against it actually happening, few have even pondered the possibility of it.  Yet as the pre-fight spectacle of trash talk and "Gotcha Hat" begin to fade in favor of the coming reality that a 44-year-old retired pound-for-pound king is actually going to trade punches in Sunday's eight-round exhibition (Showtime PPV, 8 p.m. ET) with a 26-year-old YouTube star who will stand six inches taller and outweigh him by upwards of 50 pounds, what if the unlikely becomes reality? Should Logan Paul (0-1) actually defeat Floyd Mayweather (50-0, 27 KOs) at Hard Rock Stadium in Miami Gardens, Florida, what would that even mean? Would the sun still come back up on Monday morning? Would the sport or the reputations of either fighter ever be the same again?
