#4 Boxing attraction Conor McGregor

If Conor McGregor gets tired of getting leg-kicked and taken down, he can always come back to the squared circle for more money fights against boxing's biggest stars. The Irishman, after all, already dabbled in the sport when he made his debut pro-boxing debut against Floyd Mayweather in 2017.

The highly-anticipated crossover bout befittingly dubbed 'The Money Fight,' earned McGregor a whopping $130 million. With two of the biggest draws in combat sports crossing paths, the grand event recorded the second-highest pay-per-view buy rate in history.
There are a number of high-profile boxers 'The Notorious' could partner with to generate the same amount of buzz that Mayweather-McGregor did.
It's been previously reported that McGregor and Manny Pacquiao tried to put together a boxing mega-event, but it was nixed after the Irishman's loss to Poirier at UFC 257. It's also no secret that Jake Paul has been trying to coerce McGregor into fighting him for a long time.
#3 Hollywood star Conor McGregor

In previous years, it had been heavily rumored that Conor McGregor would appear on HBO's acclaimed series Game of Thrones. Due to his relationship with GoT stars Liam Cunningham and Hafthor Bjornsson, Hollywood insiders speculated that a McGregor cameo in the phenomenal fantasy drama was a likely possibility. However, nothing came of it.
More recently, the Irishman has revealed that he was very close to making an appearance on the popular historical drama television series, Vikings. However, McGregor said he had to pull out at the last moment for reasons he did not disclose.
Evidently, McGregor is somewhat interested in pursuing an acting career, although he never pushes through with the opportunities he's been given. That could very well be due to his busy schedule as a UFC star. If he does retire from MMA, though, he'll have plenty of time to appear in TV shows and movies.
Ronda Rousey, Randy Couture, Georges St-Pierre and Quinton 'Rampage' Jackson are among the former UFC stars who found success in acting. There's no reason to believe McGregor can't follow in their footsteps.
