I think Cormier is just trying to call out somebody who he thinks will take the fight because he doesn't want the card cancelled and to end up in Strikeforce purgatory.
That was my thought as well. It's at least as good of a fight as DC fighting Mitrione. I don't think Dana and company will let this be cancelled, I think they want DC in the UFC sooner rather than later. Of coarse anything is possible and if Pat connected and knocked DC out it would sure set DC's career back. At 33 he doesn't have that many years left.
