I never heared that Ray Sefo got 3 Milions,is this your source.I think 10-20millions$ for 1 fight is litle more money than 3 milions per year and only one year not every year.Are you watched Ray Sefo boxing match vs b-level fighter.He was brutaly knocked out like never in K1 fights and his boxing was best in K1.In K1 final 2010 were fat Ray Sefo and fat Mighty Mo.Is Overeem(steroid user) better athlete than Wladimir Klitschko?
Jerome LeBanner was a undefeated professional boxer under Don King promotion before he turned to kickboxing. Mike Bernardo held at some point a HW title in boxing.. Apart from the champions and belt holders boxers earn aprox. the same as a top 10 K1 fighter.
Jerome Le Benner(6-0) is undefeated vs this kind of opponents. [ame]http://www.youtube.com/watch?v=Yp5LtuB6ygY[/ame]
