I believe that Crawford has no quarrel if he will just receive a 40% of the purse cut because he can still earn some good clean money on PPV's revenue as well as this fight will likely be with Spence's promotional camp, PBC.
Agree, 40% for Crawford is expected to be big as their fight is a much-anticipated fight long and many viewers will spend money on it. Much better maybe before that he will have a guaranteed $10M to receive if he fights Pacquiao, no set purse split.
On the other hand, Spence can surely gather lots of viewers and will help contribute to the PPV being sold out again, as usual.
40% for Crawford, if he insists, I doubt Spence will still be interested in fighting him.
Crawford receiving a 40% slice on the purse will be his biggest pay out on his whole career aside from the PPV revenue that he will also get, it's already a win-win situation for him so I think he won't insist much bigger share and yes, he needs to think twice before he gives an answer because that could be his greatest regret in his career. That $10 Million offer to fight Manny Pacquiao won't mean much if gets a fight with Spence.
I think that would be 1st quarter next year. My reason is, they don't want the fight to be held close to the date of the possible trilogy of GGG and Canelo although since the latter loses, there still a match planned involving these 2 greats around September like GGG against an still unknown boxer and Canelo vs Bivol possible rematch.
We will see this upcoming weeks if there would be some revelation that both camps have come to an agreement where their fight will happen this time, also Spence is still in a good condition after his fight with Ugas, so maybe somewhere in November or December will be a good schedule for these two.
About Canelo and GGG's trilogy, I ain't sure now if these two would clash in the expected month because Canelo would likely seek some revenge first before giving GGG a fight.
