I'm not a fan of either fighter. However, they are both very skilled in their own rights.
I see this one coming to a decision. Diego has had a hard time finishing opponents. The Riggs fight was a lucky win and based off of a (close) controversial knee.
Koscheck has had better finishes, but has fought fighters lower on the pecking order.
I see this one going to decision.
As for the winner of this fight getting a title shot. Well, if the UFC gives Hughes a shot first, I see the winner of this fight having to fight one more fight before they get to fight GSP (er... I mean the winner of the putative GSP Hughes fight
If Hughes does not get the immediate rubber match with GSP (which I don't think he deserves given his lack lustre performance against Lytle), I see Hughes fighting the winner of the Sanchez Koshcheck fight.
Personally, I just wan't Sanchez to fight GSP and get it over with. I am tired of hearing people whine about Diego getting a title shot.
