#4 Nick/Nate Diaz
While technically it makes little sense for GSP to fight Nick Diaz again considering his absolutely dominating performance against him the last time they met in the octagon, it is sure one that would rake in the numbers for a big PPV.
It would also make less sense for UFC at this point to lose another star in Nick Diaz by making him lose to St.Pierre twice and putting him on a 4 fight losing streak, something that will only make it harder to sell him as a main event on any big PPV.
It is also highly unlikely that Nick would even take this fight since we know he already turned down a rematch against Robbie Lawler, one who matches up better with him as opposed a technical wrestling-dominant fighter in St.Pierre.
But the fact remains, it could be a huge tune up fight for GSP and if he manages to drop to 155 which he absolutely can, he could even fight and dominate an equally, if not more famous younger Nate Diaz.
Is it worth squashing one star to put over another? In this case, it remains to be seen.
