Personally, I hope JMM fights Pac next. They need to settle things once and for all - and there will be no doubt this time around. Manny was a one armed fighter for their first two fights, IMO I could see Pac totally outclassing JMM and possibly K.O.ing him in the middle rounds.
I'd like to see Pac fight JMM (@ 140), just to see Manny put all the ney sayers to bed.
