In just a few days, Floyd Mayweather will take to the ring for one last time to defend his Welterweight title against Andre Berto on Sept. 12 at the MGM Grand in Las Vegas. After this fight is over, we will either see Mayweather match the legendary 49-0 mark set by Rocky Marciano, or, see the upset of the century if Berto can pull out the victory and put a single blemish on Floyd’s currently untarnished record.

Bryan Altman is, for some reason, an unabashed fan of the Rangers, Jets and Mets. If he absolutely had to pick a basketball team it would be the Knicks, but he’d gladly trade them for just one championship for either of his other three teams.
