Modern day equivalent to RJJ vs James Toney?

[Big_d135]

What would be a modern day equivalent to RJJ's victory over Toney? I was just wondering to try and get an idea about how big a accomplishment his win was.

Im not talking about in terms of style but fighters now day who would have a similar stature to them two back then.

Calzaghe-Kessler if Mikkel won.But he didn't.

It's hard to find an example.

Haven't seen an equal fight to that fight in terms of how big the accomplishment was. But I think that if Pacquiao beats Mayweather, that'll be sorta close to RJJ beating Toney, I think?
