Both fighters will need to eventually fight the other if they care about being "the best"
Otherwise it'll just be the same narrative every post-fight "yea that's cool you beat so n so tonight, but when are you going to fight ____"
No different than AJ vs Wilder for the last couple years, even tho AJ was probably making more than Wilder, Spence, and Crawford combined, to just fight
whoever in the UK. Of course after what Ruiz did, we'll see what happens if AJ wins his belts back.
Spence can be comfortable just fighting his merry-go-around of PBC comp and Crawford can be comfortable fighting whoever those guys are, but both know their defining fight is vs each other.
