Lewis EASILY, seriously this thread is not only an insult to Lewis but to boxing in general and doesn't require explanation. Lewis unified the title beating champions, cleaned out the division and beat a Vitali Klitschko no one beat to this day on short notice and as a 38 year old out of shape. Lewis' resume makes Calzaghe look like a puppet. Take the long list of fighters Lewis beat and compare with Calzaghe who has like 3 names worth mentioning in his resume and those 3 wins can be criticized as normal wins. I would honestly compare Lewis' wins rising in heavyweight ranks BEFORE losing to McCall with Calzaghe's entire career, if you want to compare anything beyond that you won't be able. If you compare anything beyond that Calzaghe ends up looking beyond horrible.
