Joe Calzaghe is very good, and many call him overrated, which could be true, but I still give him a lot of credit. He is one of the very best Super Middleweights in my opinion. Also a pretty good Light Heavyweight. At Super Middleweight he made 21 successful title defenses. He beat the likes of Jeff Lacy, Peter Manfredo Jr., Mikkel Kessler, Bernard Hopkins, and Roy Jones Jr., Retired 46-0.

He would have a huge size advantage here because Sugar Ray Robinson was a natural Welterweight and Middleweight. But, great as Calzaghe was, Robinson was the greatest of all time, and I think he'd dominate Joe Calzaghe.

I don't really know how to call this fight, but Calzaghe doesn't even compare to Robinson in my opinion. He was dropped by Bernard Hopkins, who wasn't the hardest hitter, and I think his speed wouldn't bother Sugar Ray at all. Robinson was just as fast, and probably more powerful too. Maybe Calzaghe could do well early on, but I think Robinson wins an easy unanimous decision.

Robinson UD12 or 15.

Sugar Ray Robinson. Nobody beats Sugar Ray Robinson in his prime.

Sugar Ray Robinson would give him a beating.

A natural 147 pounder vs a natural 168-175 pounder? Not a fair fight, Ray Robinson is an all time great fighter, but to put him up against another great fighter who has a 20 pound weight advantage is just a bad idea. Good big-un usually beats a great little-un.

Sugar "Ray" Robinson was light years ahead of Joe..................No comparison. Sorry.
