Of course, this is a interesting match, both knows how to promote the fight thru trash talking and antics during the press conference. I'm seeing Conor attacking Logan's lack of experience here as compare to himself which has been in the Octagon and with a lot of experience under his belt.
Conor can handle the marketing with minimal effort yet make a huge impact because people already know him, his badass attitude in MMA and his hit movie, where he plays the same badass persona, keep him in the spotlight. He's everywhere, and people love watching him. That’s why the promoters offered such a massive payout for this fight. It’s guaranteed to be a blockbuster, especially in a country with the largest population - India.
That's where McGregor is good in promoting his fights that's why his every fight in UFC is record breaking. And then his fight with Floyd is a record too just behind Floyd and Manny. So he is a bankable star because of this loud mouth and fans love him for that.
That's why even if he makes a comeback in UFC after missing several years, he could still make a lot of money as fans are willing to watch him. That's why we are not surprised about his massive payout here as the backer of this fight can also profited big from him as he is a cash cow and a magnet.
