Nonoto ATG! A notch or two below atg level. His best work was at 112 -118 where he had a big height advantage over boxer in the division. That's the only critique he has on his shoulder but otherwise he is a HOF..
Forgot about Hopkins and Jones, clear ATGs, Lewis and Holyfield too, although I wouldn’t really consider them last generation, more like the generation before. Wright and Calzaghe aren’t though, but they’re ATGs in their respective weight class, with Calzaghe being the GOAT at 168. When I think of ATG, I think of the 100 best boxers of all time and boxing has a deep and rich history spanning more than 100 years. It takes a lot for someone to be an ATG, you have to do something really special to earn it.
Agree with most of the posts so far. HOF certainly, ATG probably not and I was a huge fan of his. His accomplishments were considerable, but ATG is an accolade thrown out far too readily these days. Out of those mentioned above, I would say only Jones, Hopkins, Mayweather, Pac, Lewis and Holyfield fit the bill.
