Calzaghe is top 25 material, not sure about top 10, and top 3 no f*ckin way. I like Joe alot and he has had a great career but I think people are getting a bit ridiculous with this top 3 or top 5 stuff. Top 10 maybe but its very debatable.
Probably a bit better that top 15 this era. I got him No.2 for Wales....thats mainly because I don't have a great amount of knowledge on Welsh or Driscoll. But anyway the acheivements you listed are still remarkable and he should be applauded.
by stack you mean 2???...... but newayz, i got him in the top 75 of all time, not that i've made a list or plan on making one, but that seems like where he'd fit in.... and i agree resume wise he probably is the #1 SMW of All Time...not head to head though
