If the aforementioned fighters have been given the chance to make $40m+ in a single fight against Pacquaio, would they have have botched the fight because of a 50/50 compromise?
It depends on how Pacqauio was viewed and held up against them.I think Leonard and Hagler would demand bigger splits if they were rated considerably more than Pacquaio.Difficult question,but think it depends if they were standing on their own in the ratings similarly to Floyd.These guys had far better competition,but speaking for Ray,I think he would want a bigger split just to gain a psychological edge.He was a master of mindgames.
Leonard probably would have but Hagler wouldnt give a damn and fight anyway, like he gave into all of Leonards demands.
Maybe Leonard due to his drawing power and tendency to usually command the lion's share of the purse. Then again, from what I've read, his guarantee against Hagler was actually less than Hagler's was.
