Conor McGregor Dominated Álvarez in UFC 205 with 1.3 Million PPV

But MMA is very different from boxing, here there is only one dimension of combat and Mayweather understands it better than anyone in history: it's about hitting and avoiding being hit.

That's how he reached the record of 49-0, one away from 50, surpassing Rocky Marciano, 'Money's' obsession, who also holds the highest revenue in pay-per-view sales in a single night, in May 2015 when he fought Manny Pacquiao and it is estimated that up to 4.4 million screens were purchased.

Realistically, Conor has no chance of defeating him in 12 rounds if it comes to the scorecards. His dozen amateur fights in Ireland before migrating to MMA do not support him. Under no logic could he beat the pound-for-pound best in the world.

That's Conor's virtue; he has always challenged logic, even when he lost to Nate Diaz he was a 5-1 favorite. No forecast is valid with the man who has fought from 145 to 170 pounds in the octagon and signed at 154 for his professional boxing debut.

Mayweather knows that 'The Notorious' is disrespecting boxing and wants to shut him up before the sixth round. Those same initial chapters are where Conor has his opportunity. Only through knockout, because in the final rounds he won't even be able to see the shadow of his opponent, in his career he has had a 25-minute fight and he faded, in 36 it could be disastrous.

Conor has more punch and precision than Floyd and probably speed is a factor in favor of the 28-year-old man facing the 40-year-old. Both have been preparing for months and the American knows that this is his only chance, that no one will help him raise even a tenth of what this fight will do. He was the only opponent who could put the nine figures on the table: over 100 million dollars.
