Most difficult champ to successfully defeat in first world title fight?

[Holywarrior]

hearns-cuevas.. cuevas had around a dozen defenses with only two or three going the distance. this was back when the WW division was loaded too.

mccllellan-jackson.. jackson was 46-1 (44) going in. his lone loss being to the atg mike mccallum what must have been 6-9 years earlier, in those years he had been fighting almost exclusively at championship level knocking out everything that moved.

dawson-adamek.. tough, tough fight. people didnt quite reaize it at the time but we know now what a beast adamek is. keep in mind the only other fighters to beat adamek were heavyweights and he was a dominant champion at both 175 and 200lbs.

jones-hopkins.. same thing, people didnt know just how great hopkins would turn out to be. granted he was a late bloomer and jones didnt really beat the best version of hopkins back in 93, but he was no pushover thats for damn sure.

toney-nunn.. nunn was considered one of the best p4p fighters in the world and many had already crowned him the future p4p king, he was undefeated and boxing in his backyard. to make matters worse toney hadnt had the right kind of fights going in to prepare himself for nunn and was making a huge leap in class.

Was Nunn vs Toney really Toney's first title fight? Didn't know that.

Yeah it was... I remember thinking in the late 80s that nunn was going to be an atg... The way he beat Frankie Tate,,, toney was a virtual unknown at the time in early 91 and looked completely outclassed for about 8 rounds... Then boom, toney ended it in a hurry in the 11th...
