What was the upset of each decade from the 1920s to the 2010s? You can only choose one per decade. Let's start off with a nice, easy one - 1990s: Douglas KO10 Tyson. There - that's that one out of the way (unless anyone disagrees?) Now the real thinking begins...
80s is easy. Honeyghan over Curry. 00s is also easy. Tarver over Jones. I think 70s is Ali over Foreman. Ali also scored the biggest upset of the 60s over Liston. Although, maybe the biggest upset of the 60s is Harada over Jofre.
No way. It was a big upset but where Napoles was in 1975 compared with where he was in 1970 is what makes the Backus loss the bigger upset.
I guess it has a lot to do with whether we’re talking casuals and the general public vs. boxing insiders. Everyone knew Ali was older BUT he was fighting a novice who had drawn with Scott LeDoux and won a 6-4 decision over Alfio Righetti. He was known from the Olympics but this was seen going into it as Ali taking an easy touch before a fourth fight with Norton ... where people probably would have expected Ali to lose in his swan song. Leon was a 10-1 underdog.
What Jel said. Ali was a washed up old man when he fought Spinks. His aura of invincibility was well gone. Foreman was at his peak and thought to be unstoppable. Many feared for Ali's life. Just in terms of its significance, Ali-Foreman is the quintessential upset of the 70s.
Although Tyson-Douglas is far and away the biggest upset of the 90s, a sleeper pick is Toney over Nunn. Toney was completely unheralded coming in, and Nunn was considered the third best fighter in the world behind Chavez and Whitaker.
There were actually a lot of big upsets in the 00s now that I think about it. Jones-Tarver was by the far the biggest, then second is Rachman over Lewis. Third is either Forrest over Mosley, Barrera over Hamed, or Pac over Barrera.
I like this thread, and since I'm not overly familiar with odds and such, I'll put my own spin on it and just list some of my favourites. 1940s: Pep vs Saddler II 1950s: Charles vs Louis 1960s: Scott vs Ortega I 1970s: Pops vs Galíndez 1980s: Watson vs Benn 1990s: Benn vs McClellan 2000s: González vs Michalczewski
