Floyd Mayweather is expecting to make more than $300 MILLION from his fight with Conor McGregor, which would break down to more than $8 MILLION per minute in the ring. The undefeated boxer came up with the figure in Showtime’s recent All Access: Mayweather v. McGregor preview. May weather said:I mean, am I the highest-paid athlete out there? And just coming back? We not talking about no contract. We not talking about no contract for no 4 years, or no contract for no 5 years. I can do it in 36 minutes. $300 (million) or better. In 36 minutes.
