What was the split Crawford agreed? did he agree about getting 40% only of the total revenue? If that's true then Spence has no excuse not to get this fight into reality as despite it's an undisputed championship fight, Crawford still give him an edge on the revenue split.
If that is true, then Crawford really wanted to make this fight happen despite getting the low income in this fight. Therefore, if Spence won't gonna agree with it and he will still decline until they get old and finally retire from boxing, then the blame is on Spence. I mean, come on man, this is actually a slap in the face to him because this is how Crawford really wanted to prove to the world that he can also beat Spence with no problem just like how he beat his past opponents.
