Mixed martial arts and boxing share many of the same fans.

Still, there are a few out there, a few MMA fans, who just can’t enjoy boxing for one reason or another — and vice versa.

One thing that really gets under the skin of some of those partisan MMA fans? The disparity of money involved in the two great sports.

It drives these folks a little crazy that a MMA star like UFC Light Heavyweight Champion Jon Jones, one of the biggest names in the sport, receives a payday of $500,000 to headline UFC 182 last year.

Granted, that may sound like a lot of money… and it is, for most of us.

However, when you take into account that the UFC 182 pay-per-view event scored about double the PPV buys of  the Miguel Cotto vs. Sergio Martinez middleweight title bout a few months prior — but Cotto alone enjoyed a $7 million guaranteed payday — it doesn’t seem so much.

In fact, Cotto’s take dwarfs the total payroll for the entire UFC 182 event, which was $1.3 million.

The discrepancy is staggering — and never more than in the biggest fight sports event of the year, and possibly any year: the welterweight boxing showdown next month between Floyd Mayweather, Jr and Manny Pacquiao.

Last month, Kevin Iole of Yahoo! Sports reported that Mayweather could earn as much at $180 million for the bout.

Yesterday, Dan Rafael of ESPN reported that the latest record to be set by the Mayweather vs. Pacquiao mega-fight is not by the fighters, but the mat on which they will do combat.

On his official Twitter account, Rafael noted: “Amazing $ stat for ‪#‎MayweatherPacquiao‬: It’s obliterated ring mat sponsor revenue record: $12M with spots they can still sell.”

Yes, $12 million has already been spent by sponsors for the mat on which they will compete… and we’re still a month away.
