A Floyd Mayweather Jr. vs. Manny Pacquiao rematch has long been in the air, and the chances of that have gone from possible to none.

Officially, both boxing greats are retired. However, that does not mean that seeing Mayweather and Pacquiao fight again cannot take place.

Today's reality is that exhibition matches may make more money than official boxing clashes. Mayweather has had his share, while Pacquiao also started doing that against several personalities. The only difference is that both have taken on opponents that are not professional boxers.

Hence, a Mayweather-Pacquiao 2 is likely to be an exhibition fight but would be the first time featuring actual boxers.

Some may pay to watch while others may not, Bleacher Report suggested. Whether it happens or not, Mayweather and Pacquiao are expected to earn another big payday, although it may not be the same as the millions they got in their initial meeting in 2015 via ESPN.

Hence, what would it take for a Mayweather vs. Pacquiao II to happen? Here are some important factors to consider.

1. Will there be backers for a Mayweather vs. Pacquiao rematch?

Although nothing is set in stone, a critical part of making a Mayweather vs. Pacquiao II happen is if groups are willing to back it up financially.

Some teasers came out on social media that a rematch between the two boxing legends would happen in May 2024 via the Dragon Boxing Stable Facebook page.

However, a reliable source on the Pacquiao side said that while it is possible, nothing is set in stone via Sports Bytes Philippines. The same source adds that it could get some clarity this October if the investors are willing to back up a potential Floyd Mayweather Jr. vs. Manny Pacquiao rematch.

2. How much money will be up for grabs?

Mayweather has been known to agree to fight only if money talks. The same holds for Pacquiao, who has maintained his fortunes through other means.

Despite both fighters being retired, it would take millions for the rematch to happen. As mentioned earlier, this will likely depend on whether there will be financial backers for the rematch.

Aside from the prize money, the pay-per-view revenue can add to the earnings of both Mayweather and Pacquiao. The alleged May 2024 clash of Pacquiao vs. Mayweather could materialize if the pros outweigh the cons.

3. Will Mayweather and Pacquiao have enough left in the tank?

Although Floyd Mayweather Jr. and Manny Pacquiao have ensured they are in top shape, it will be interesting if they have enough for another boxing clash.

Of course, both may take it easy and engage less. Mayweather is a master in this regard, opting not to exchange punches and using his wit to frustrate his opponents.

Pacquiao got a taste of that in 2015. While he complained of that tactic, a rematch could also follow the same script.

Considering Pacquiao is 44 and will turn 45 in December, it may be in his best interest to also fight wisely. On the other hand, Mayweather is 46 and will be 47 if the May 2024 clash does happen.

Regardless of whether they take it lightly, both know that one punch will make a huge difference. If so, the Pac-Man could be tempted to drop a haymaker - assuming he can catch a dancing Floyd Mayweather Jr.
