I think maybe because Crawford doesn't really actively pursue into unification fight or any fight that would strategically put him in good position to make his rivals chasing him. He missed the chance when Spence concluded the unification fight deal with Porter. And now, to make it even with Spence, he must beat Pacquiao for his WBA title. And we all know both Pac and Spence are with Al Haymon, this won't be easy. If I may rate his welterweight career, he is worse than Loma in his career in 130. Though Loma had difficulty to unify (and rematch Salido), at least he fought Sosa, Walters and Rigo. If he can't unify at all, he should move class.
probably yes, he has to be really, the resume is there, he has better opposition than Crawford. I have Crawford the more i think about it behind Breidis, hes cleaned out a division and is the goods, you cant put Crawford before him, hes fought way better opposition
