Bro no fighter is perfect in all facets instead of looking at the 1 thing he isn't good at look at all the area's he is good. Even then for a guy with bad footwork he managed to catch movers like Trout and Lara. Khan isn't nearly as good as them at evading so Alvarez should have no problems.
Hunter wouldn't let Khan anywhere near Cabell he wouldn't be allowed to mention his name let alone be in the ring
