He would stand toe to toe and get Tszyu out of there somewhere around the 8 or 9th. And Charlo and him would have a violent back and forth 12 round war. Mendoza loses a valiant 7-5, 8-4 decision there. Definitely nothing to sneeze at.
He could fight in the pocket but probably not the best strategy. Pressure would get to him at some point in the fight and he would fold in the late rounds with Tszyu, With Charlo, I don't see Mendoza being able to sustain a beating that long.
