I find this phenomenally annoying. Cain sat his ass on the shelf for most of his tenure as HW champ. After winning the belt, he got blitzed by JDS in his first defense. He then fought Bigfoot and JDS again and again over his next four fights. And he took AMPLE time in between those fights. He lost his recent defense thoroughly. Dominated and finished. There are some other very interesting fights for Werdum, with at least 2 of them offering him a chance at redemption against guys he lost to in the past (JDS and AA). And God forbid, but what if Cain gets injured again leading up to this fight? It will be a giant waste of time, and Werdum isn't exactly a young man either.
