I guess it all depends on how you look at it?.....he is the longest reigning SMW champion and has had some good names...the bigger names early on in his career were past their best though,,,Brewster, Eubank etc....then he has beaten the two guys considered the biggest threats to him in the last 2 or so years in Lacey and Kessler...A problem for not only Calzaghe but any SMW is the division has never been chuck full of talent...more or less a stop over point for most.....He has kept a stronghold on his title though and has garnered a P4P spot....his wins have been pretty dominate...he may not become an ATG over all and end up in the top 20 but he will go down as an ATG SMW perhaps the top SMW of all time....

The way ATG's are rated is funny like I said it is all how someone views ATG
