Does Calzaghe have the opponents to be considered a true ATG?

[ICB]

Just wondering, he's first ballot HOF of course because of his record alone...but does he have the proper opponent resume to be mentioned with the all time greats?

Nope it isn't but neither was Barry Mcguigan's so there you go

I don't think anybody considers Barry McGuigan an All Time Great

I actually misread the question my bad.
