Ok, this current generation of fighters has featured 3 great Mexican featherweights:
Erik Morales
Marco Antonio Barrera
Juan Manuel Marquez

For the sake of this thread, let's assume that neither Barrera nor Morales ever fights again (which I hope is true for the sake of their health) and that Marquez will now face Pacquiao in a rematch later this year.

1. As of right this minute, how do you rank their careers?
2. How would Marquez's standing change if he wins or loses against Pacquiao?
3. If Morales and Marquez fought in their primes, who would have won?
