About making money then its no brainer that these dudes are really raking up some bucks because exhibitions wont be pushed on
if there were no demand or if they cant really get some revenue.
Floyd Mayweather knows he can make millions fighting exhibition bouts and he made over $9 millions dollars fighting Nasukawa who was much smaller than him and now he is fighting another exhibition match against a fighter who is much bigger than him but he knows he will be making more than $10 millions for the fight and they know very well that the weight disparity will create interest in the bout.
