if wb wanted to be pk, then he would need to be stronger than roger.
roger didnt have to be stronger than wb because wb had no interest in roger's goal. rivalry can only come when we are chasing the same thing.
roger wouldnt be pk if wb wanted to conquer the grandline too without taking wb out. as far as we know, he couldnt. they were on par.
as for garp, they also fought multiple times and were on par
roger did not surpass those two in strength.
