Where would Crawford rank among great 140 pounders

Exactly but if he makes waves at 147 and then campaigns at 154lbs each for a few years he can still reach ATG status based on accumulative body of work despite not ranking among the very greatest in any one division.

 

It's too zoo to judge him and he won't be at 140 long enough.

 

Agreed.... I would think that anyone who is going to be considered an ATG in any division would have had to have done the majority of their work in that division. That being said, FMJ, Pac, Duran ect... all competed there at one time and are all widely considered all time greats in their own right.

 

Then he would need to stay there and defend his unified status against top tier competiton. Tszyu is an ATG JWW because of that reason. Many fighters had a heck of lot more fights that Tszyu but few can say they did what he did.
