Difficult. Ramirez has had just a few fights at LHW and is still untested. Both have similar styles and work rates. I think Smith has the bigger heart, a tested chin and would take it.
It is hard to gauge Zurdo as his competition has been so poor. We will get some answers after the Bivol fight. Smith is starting to remind me a bit of Andy Lee. He can be out hustled and beaten by he always has the hook that can turn the lights out at any time.
Jesse Hart brutally rocked Zurdo several times, Yunieski Gonzalez had him out on his feet. Callum knocks him unconscious.
Zurdo is naturally bigger than Canelo, and has been hitting harder since moving upto 175. Its not entirely impossible for the bigger Zurdo to land something big that Smith doesnt see. Zurdo would KO him. Sowwey if that hurt your feelings green pants G-A-L.
