Who should JMM and Pac fight before they retire?

I would really like to see Marquez vs. Campbell and Pac vs. Diaz. I think right now those are the best fights to be made at lightweight.

pac-jmm 3 will be good for both fighters and great for boxing in general... jmm has a few fight left in him and for pac he is retiring next year, we need to have this fight by end of next year!

Margarito obviously.

Since Pacquiao is busy with DLH, I think JMM should fight Campbell so that he would have 3 of the alphabet titles as well as having the Ring belt if he wins and then they can fight each other for lightweight supremacy and to determine the pound for pound number 1 fighter.

I think both guys should make their final bout the JMM and PAC 3rd rematch, then retire. But until then I think they should continue doing what they are doing, Id like to see a possible Hatton fight next for Pacman, JMM vs Campbell of course and Diaz. Youre forgetting that JMM is 35 years old now. He only has a few fights left in him while Pac is still in his prime. I think its very unlikely that the two would retire at the exact same time.
