MAB slightly over EM, as far as JMM and Pac that remains to be seen, they still have some fights left in them. At 122 MAB over all of them, period. He was the smallest of the bunch imho and didn't carry anything over FW nearly as well as Pac and JMM.
Pacquiao Marquez (im on the minority here but beating casa and juan diaz in devastating fashion, and also arguably losing to pac gives him the right to be labeled #2) Morales (he beat pac convincingly 1st time and has a stellar career all throughout) Barrera
Pacman Barrera (my fav fighter) lasted 3 generation (Mcinney - Hamed- Marquez) amazing Marquez Morales
