Read through the thread and might of missed the fight being mentioned:
Kimble v. Crowder. When Kimble took care of Crowder (I liked Crowder but I can't say it was the jersey, a fight is a fight until the end) it was at Crowder's peak. It was also the reason why St Louis traded for him as they thought he could take on Probert... and we all know how that worked out.
You could put a few Godard fights in here as he seemed to fight down to his opponents level... I remember being pissed when Konopka took him on and he looked disinterested... and the Stock fight still has me scratching my head.
McKenzie beating Twist put him on the map. That was his coming out party in a sense.
