On accomplishments mainly, Roy was the most talented. By 95, Whitaker was on his way out.
1. Mayweather (5 weight champ, 50-0, beat 23 champions)
2. Pacquiao (8 weight champ, most exciting fighter of all time)
3. Jones Jr (won a title at freaking heavyweight, started at 154, most naturally gifted boxer ever)
4. Hopkins (20 middleweight defences, won light heavyweight title as an old man, oldest champ ever)
5. Marquez (3 weight champ, Pacquiao's nemesis, one of best combo punchers ever)
6. Canelo (4 weight champ, amazing combo puncher, great defence and offence)
7. Calzaghe (21 super middleweight defences, won light heavyweight title too)
8. Ward (2 weight champ, won super 6 tournament, first guy to beat Kovalev)
9. Golovkin (20 middleweight defences, cleaned out his division multiple times, only one highly disputed loss)
10. Lewis (besides two blips which he avenged, he was the most complete heavyweight in a strong era, beat everyone he faced from Holyfield to Vitali Klitschko.
De La Hoya could easily be in there along with a few others. Canelo will probably catch Marquez within the next year and maybe even get as high as #3 (on accomplishments).
