Floyd Mayweather and Conor McGregor might not be any closer to meeting inside a boxing ring, but the verbal sparring between the two fighters hasn’t stopped. Mayweather threw the latest jab Thursday, comparing his net worth to that of the MMA star.

Mayweather’s most recent comments were in response to an offer made by UFC president Dana White. Appearing on “The Herd” on FOX Sports 1 last Friday, White offered to pay both Mayweather and McGregor a guaranteed purse of $25 million to make the much talked about boxing match a reality. White told Colin Cowherd that a share of the pay-per-view revenue could be worked out with Mayweather.

While a $25 million offer to just about anyone else would suffice, it isn’t up to Mayweather’s standards. The undefeated boxer made well over $200 million for his fight with Manny Pacquiao two years ago, and he laughed off White’s proposal.

The numbers posted by Mayweather likely aren’t accurate, but there’s no question that he is worth exponentially more than McGregor. Mayweather is the richest fighter in history, while UFC doesn’t allow McGregor to make anywhere near what the top boxers get paid.

Since he retired in September 2015, Mayweather has maintained that it would take a guaranteed purse of at least $100 million to get him back in the ring. Mayweather was guaranteed $32 million for his final fight against Andre Berto, and he made millions more from the PPV revenue. Mayweather has earned $700 million for his 49 career fights, and he’s been guaranteed at least $32 million for each of his last seven fights.

When McGregor set a record for guaranteed money for his UFC 202 fight against Nate Diaz on Aug. 20, he earned $3 million. McGregor likely made just as much for his UFC 205 fight against Eddie Alvarez on Nov. 12, and he said he expected to earn $40 million total for his three fights in 2016. It’s unknown exactly how much money McGregor has made from PPV revenue.

Several obstacles stand in the way of making Mayweather vs. McGregor a reality. McGregor isn’t a boxer, and he would have no chance to challenge Mayweather inside the squared circle. Mayweather certainly doesn’t need the money, and he might not want to return for a novelty fight.

There is interest from the public, and it’s at least possible that the fight could be made if the money is right. But White’s recent proposal won’t come close to getting the job done.
