1. Brock Lesnar
Brock Lesnar’s probably the most famous guy to try his hand at MMA. There was such a buzz when he announced he’d be stepping over to the octagon, and he had a whole load of success in MMA too. The guy does what he does for money – it’s a major motivator for him. He’s done well on that front, and has gotten the highest ever fight purse in UFC history. Now he’s back wrestling, only appears now and again, but still demands megabucks, is at the top of the highest earners list. Life is roses for Brock right now.
