With all the will they, won't they of the Pacquiao-Mayweather negotiations, it got me to wondering of previous times when fights really should've happened but never got off the ground.

What fights would you have liked to have seen, that were just never made.

(I mean legit fights that could have potentially happened, not fantasy match ups ie Tyson vs Ali, etc.)

I couldn't find a thread that had discussed this recently, so apologies if I'm rehashing some tired debate.

I remember back in the day when I first got into boxing in the UK, Prince Naseem Hamed was the top dog, and a fight with Erik Morales was mooted but never happened after Marco Antonio Barrerra exploded the Naz myth.
