I'm thinking the fight can happen at this point should both Floyd and Manny keep winning.
Pacman would have to beat . . .
1. Rios
2. Paulie should he beat Broner or winner of M&M vs Lopez
3. Winner of JMM vs Bradley

And Floyd would have to beat
1. Canelo
2. Winner of Alexander vs Khan
3. Winner of Garcia vs Mattysee
