I thought the general reason for 2 fighters to go at it a 2nd time is because the fight was either won by a controversial/suspect decision, was a close fight in general, or was just so f'ing exciting that fans could think of nothing better than to see another 12 rounds of the same...

Although I loved Pac destruction of Oscar, it was not suspect, nor controversial, nor close, and I would cringe at having to watch it again.. And the only exciting thing about it was Pac, and that part you can take and throw in the ring with someone else, without giving golden panties another hack job pay day to get his ass beat again...

I think Oscar and the potential trainer who is going to have a high paying job for a few months are the only ones that would want a rematch with Pac..
