Floyd Mayweather's Most Lucrative Potential Fights to End Career

Floyd Mayweather Jr. seems to have one or two more fights left in his career. He is committed to fighting once in September against an unknown opponent. If he wins that fight, he could possibly look to break Rocky Marciano's record for the longest undefeated championship career record with his 50th win to no losses.

If he reaches for the record, it would go beyond his current Showtime/CBS contract, which expires in September.

We don't know for sure, but it's hard to believe Mayweather wouldn't want to reach for the win that further validates his claim as "The Best Ever" or TBE. Assuming he fights and wins in September, here's the most lucrative fights Mayweather could have to finish out his career. Neither of these fights is likely to excite purists, but these options are about money, not the most competitive bouts.

Why it Makes Sense

One week after Mayweather's easy and tactical win over Manny Pacquiao, Canelo Alvarez blasted his way through James Kirkland in a slugfest that the casual fan wished they'd seen from Money and Pac-Man.

The 24-year-old Mexican superstar finished Kirkland with a punch that is an early candidate for KO of the Year. Here's a look at it from HBO Boxing on Twitter:

This is the type of win that gets fans' attention. Because Alvarez already has such a huge following, and because he and Mayweather's first fight was the highest-grossing bout in history before the Pacquiao contest, the market and interest for this fight has likely re-emerged.

Perhaps it wouldn't break the records Mayweather and Pacquiao are destined to set once all of the numbers are finalized, but it'll still make Money and Canelo a pretty penny.

Why it Probably Won't Happen

Oscar De La Hoya seemingly hates Mayweather and his manager Al Haymon. De La Hoya has a lawsuit pending against Haymon for allegedly circumventing the Ali Act. The breakup between Mayweather and De La Hoya's Golden Boy Promotions was a bitter one. Because Canelo is De La Hoya's fighter, there may be some serious reluctance for either side to work together to make this fight happen.

There's also the HBO/Showtime hurdle to overcome again. Right now, this one seems like a long shot.

Why it Makes Sense

This bout only makes sense from the most shallow commercial standpoint. Pacquiao has no chance to beat Mayweather in a rematch, but the two men still have the biggest names in boxing. Hypothetically, the folks in charge of promoting the fight could play up Pacquiao's injured shoulder—which really didn't appear to be much of a hindrance during the fight—as the reason for the lopsided decision win for Mayweather in the first bout.

After Pacquiao recovers from the surgery he had to repair his torn rotator cuff, he could feasibly be ready to fight Mayweather again in May. Don't let the folks who whined about the first fight fool you. If both fighters commit to trying to knock the other out in their promotional speeches, there's still some interest in this rematch.

Why it Probably Won't Happen

Initially, Mayweather said he'd give Pacquiao a rematch, but he told Showtime's Jim Gray he'd changed his mind after Pacquiao repeatedly made "excuses" for losing the fight. You can hear Mayweather address this issue in the video below from ShoSports on YouTube.

Mayweather also said in the video that he isn't interested in doing business with Pacquiao and his people anymore. Frankly, there's no need to see this fight again. Mayweather would be an enormous favorite and promoters run the risk of seeing drastically decreased pay-per-view buys if the public isn't interested enough to pay for the rematch.
