I agree, Marquez shouldn't be asking for a 50/50 deal.
The thing about Mosley, he would love to have a chance against Pacquiao because he knows "anything goes".
And Bradley, good for him for not demanding it.
Though IMO, why wouldn't you want to have a fighter have OST if you have nothing to hide either, unless you are making completely unmatched paycheck and exposure.
And have something to prove.
