I would probably take Sanchez. Esparragoza is nice technically both with his upper body and feet, but Sanchez was just so good at dictating the pace of a fight, and authoritatively as well, with tht jab and smashing in punches in bunches when guys came in range. I don't think a guy who would be using angles to get off good shots etc would be his cryptonite. Esparragoza should try to use movement as much as he can, but i don't see it materialising for him myself.
