After Hagler/Leonard most put Tyson as #1, he remained there until Busted, then J C Superstar took the vacant slot on March 17th 1990 and kept it until the Whitaker fight. The month between Tyson/Douglas and Chavez/TaylorI some had Chavez there, some Taylor, other names that were being knocked about were Whitaker and some still had faith in Nunn.
The Curry fight was more evidence Nunn could not cut it, it was a dire and sometimes a bit of a struggle for a fighter who was meant to be one of the best of the time, against a fighter (Curry) who was shot, 5 years and 13lbs past best and for all his ability, was proven to have a bit of the dog about him.
Meh, Nunn underperformed on top of goofing off in the ring. The Roldan fight is a perfect example of it, and when he's yelled at in the corner he gets serious... And ends it.
The Nunn who fought Roldan and the Nunn who fought Curry were two different fighters; Nunn was ruined by Barkley, he never regained his form.
Curry was a mere shell of his old self by then. Awful fight. Hagler was at ringside, probably thinking "I wanna get in there and smash these phonies".
It was not physical it was mental; Barkley intimidated Nunn, and Nunn lost that mystic quality that seems to glow around the very finest fighters. Post Barkley, fighters knew they could get to Nunn, unlike the Nunn who fought Rodan, Tate and Curry. Normally it takes a defeat for that to happen, but occasionally a shocking performance does it; Camacho/Rosario being another example of a fighter never being the same again despite winning and remaining undefeated.
I was going to comment on the mental aspect post-Barkley. After that Nunn fought like he was representing the AMA and wanted to see a ban on boxing.
Good call; bugger your Jimmy Young's, (never liked his show, Wogan was much better) let us talk about a fighter who was properly underrated.
