I'm surprised there's so little traction for Arguello here. I could see Sanchez being a mild fave but it's a pretty open fight for me.
Sanchez was a FW, Arguello's best was JLW, so Arguello has the edge and Wins one way or another no matter what.
Probably a really close fight, but I lean towards Arguello. He was taller, longer, more powerful, and I think had better defense. BUT, the one thing that Sanchez did better is he had better movement. Arguello primarily was a plodder, but Sanchez could fight in close or stick and move, so that versatility could give Arguello some trouble, for Aguello at times could struggle with guys who could punch but also give him some speed and angles.
