Well this is something very interesting, and I hope it happens like this, but I think that the main reason why they want the fight to happen is because of the amount of money that is involved there, I don't see that they do it for the pure interest of boxing,
I have to disagree with this. Terence Crawford is looking forward to fighting Spence for too long and now it happened. On the other hand, Errol Spence holds lots of titles, and the only title he needs to snatch to unify the welterweight division is the one on Crawford.
Obviously and of course, money plays a big factor here but a unification match is necessary between boxers with hold titles.
I can't believe you conclude already that these boxers don't have a pure interest in boxing that's why they will face each other.
