Mention of Tony Canzoneri vs. Kid Chocolate got me thinking. What are some other fights that ticked both the skilful and frenetic boxes? The original Barrera-Morales war seems like a good one to get the ball rolling... (I don't expect many, if any, heavyweight fights).
I though the first meeting between Chavez and Taylor was a pretty good action fight with a fair amount of skill.
Arguello vs Pryor. I'd mention others, but they have been mentioned already. Hell, old Duran vs Barkley too. Took gallons of skill.
Arguello vs Pryor was definitely not a skilled fight both pretty much tucked their chin and went to war
