Here's my list:

Juan Manuel Marquez vs Nate Campbell: Two veterans who should be fighting each other for Lightweight supremacy.

Manny Pacquiao vs Floyd Mayweather Jr.: Even though I think this is a fight for Floyd to win, the angles they would use to hype it would be epic! I just think it's the biggest fight in boxing that could really bring the public back in the sport. The perfect offense vs the perfect defense, former P4P #1 vs current P4P #1, Skill vs Will, etc.

Jermain Taylor vs Mikkel Kessler: It's time for Kessler to step out of his comfort zone and fight someone worth fighting. He is too good of a fighter to waste his abilities on nobodies. I still think Taylor has a lot left in the tank and his dominance over Lacy was his way of saying "I'm still here."

Ricky Hatton vs Miguel Cotto: There was a thread a while ago about this. I want to see it now.

Manny Pacquiao vs Juan Manuel Marquez: As long as these two are still actively fighting, I will always want to see them in the ring with each other.
