The Salido that beat Lomachenko is certainly better than Maidana. I had Maidana-Floyd 1 a draw. If they were somehow the same size and Salido was a welter, I'd pick Salido to edge the Mayweather that fought Maidana.
You "studied" a boxing forum "vigorously" before joining? Why would you, or anyone else for that matter, do such a thing?
