If Ward reenters the mix and beats a few more up & commers? where will he stand?

I am a big fan of Ward. I feel like he represents a part of Oakland that goes way back, and includes athletes like the late Billy Martin, who was every bit as scrappy as any New Yawk tough guy... Oakland is a tough scrappy town, at least where the hipsters fail to tread. So, without mentioning any fighter in particular, where would Ward stand if he comes back and beats continues his success? Like Floyd he may have to do it in multiple weight classes, even at the dreaded "Catch weight." But there are some guys coming up that are in Ward's kill range so to speak. Lets say he beats Usyk. Lets say Kovalev fights on and wins impressively,. Is there a point where Ward compares to Mayweather? What do you think?
