Who is the biggest cash cow ever in boxing?

Mike spent $300 million like an idiot.

Random but true! Lol

ODLH comes to mind. He was massive and those who fought/beat him also benefitted. It's no surprise that this helped Floyd enter the cash cow world, as did it help Pac as well. You became a star by beating a star. Putting star aside, it doesn't equate to being entertaining in the ring.

AJ's deal is 100 million a year + upside with sponsors and all. Add what he has already made like 80 million + vs Fatboy in the rematch. He is definitely on pace as an HW to surpass FMW if he stops fooling around, gets a real coach, and stops taking these unnecessary Ls. I could see Fury in a trilogy but Ruiz and Usyk?
