I'm going with:

1) B-hop
2) RJJ
3) Calzaghe

Hopkins has the bigger names and the better career than the other two and it's still not over. RJJ lacks the names Hopkins has but not the skill. Calzaghe also lacks the names, and his win over Hopkins is disputed while Jones was really nowhere near prime form. All are great fighters but I'm just trying to show why I'm placing them where I did.
