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

[SEANIE]

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?

You can only fight whose around at the time. he's the only boxer to hold all major belts at super middle hes made 21 defences and yes some of his opponents were not the cream of the crop, but neither were some of joe loius or larry holmes or any other champ whose dominated their division. he is the model pro and an example to all other boxers. he gets the job done. he should get in at the first attempt
