that'd be the perfect retirement plan.
GSP's here since a while ago, prime or not, he's bound to decline anyday now and I doubt he can significantly get better.
With his boy Rory climbing the WW ladder, he has to think of getting out of the way or accept to fight Rory at some point in the fairly near future.
Diaz, Hendricks, then Silva win or lose, retire on top and move on with his life as one of the greatest of all time if not the greatest (should he beat silva convincingly, which I doubt he'll do but who knows...)
Enter the UFC HOF too along with BJ
