Some tasters:
Alexis Arguello - Royal Kobayashi (brutal left hook puts hometown hero Kobayashi rocking on his back in obvious pain)
Alexis Arguello - Andy Ganigan (brutal combo primed by a devastating right hook sends Ganigan halfway out the ring for way longer than 10)
Carlos Monzon - Gratien Tonna (right hand bang on the liver humbles hardman Tonna)
Marco Antonio Barrera - Luiz Freitas (hard punching brother of Popo looks to cry? after getting blown out inside a round by savage series of lefts from a peak Barrera)
Looking forward to hearing any obscure ones... especially pre-1960's.
One thing though, let's try for once not to let this turn into an old-timer vs. modern debate. How about we stick to the punching and punching only.
