This is Nick Diaz bro. If georgey boy wants to stand and trade with Diaz (which he obviously wants to avoid) he's going to get lit up like a Christmas tree.
Personally I think Nick Diaz has some of the best boxing in MMA,and a granite chin.
He may not have the 1 punch k.o power but can definitely ware you down and stop you.
If G.S.P decides to stand with DIAZ he could be in for a very long night, especially watching his last fight where George was getting tagged by a weak stand up fighter in Jake Shields.
Georges best bet is to use his amazing wrestling, and try the ground and pound game but with Diaz having a good Jujitsu game will he want to risk it.
It definitely makes for an interesting fight, but I can see Diaz outworking G.S.P and outpointing him with punches as I don't see G.S.P subbing or K.O DIAZ.
Possibly see George holding Nick down and grinding out the decion but either way I won't be betting on this one.
