There's no problem on how much money the fight will generate but the concern is, no one is willing to a 50-50 split. Both camps have a big reason not to make it even and that's not making sense to them. It's really hard to negotiate on that part especially if both boxers have a big name.
Unless one of them will make way for a less split, then that's a good step for the fight to push through. The only time I remember seeing Crawford likely to accept a much less split is when his name becomes a candidate as an opponent to Manny Pacquiao (correct me if I'm wrong here). He accepts that because never in his career he got a chance to have a big fight.
Spence is not willing to take an even 50-50 split on Crawford, he already said that after he won against Danny Garcia.
"He gotta take a backseat and take that 60-40 [split] or 70-30, whatever we give him.", Spence stated.
The splitting is the most biggest problem and the hardest part while arranging a fight because it will really take a long time as both of the boxer is not willing to take an uneven split especially if both of them have big names like Spence and Crawford.
Well, Crawford is calling at Spence lately but the question is, if ever Spence will acknowledge and accept to fight Crawford then is he willing to accept what Spence's deal for him like a 60-40 split or worse 70-30? Spence is very vocal on his rank in the industy and just like the source said, he is the bigger dog so he is more entitled in the purse.
