It's his stupid management hand picking fights for em.
Overlooking the Brock Lesnar title fight had to have been one of the biggest blunders of all time. I'm quite certain he would have dethroned em taking the UFC title in the process. THEN if he lost to JDS or Cain it would have been a passing of the torch. At least like Big Nog he got his shine in the UFC. But nope...instead his management committs career suicide for him.
