I wonder who he considers to be "really good" contenders? Off the top of my head I honestly cant think of one person in SF's WW division that could pose a legit threat to Diaz. I guess it's easy money for Diaz. I'm sure he got a sweet deal from SF and he gets to beat up guys that really dont pose much of a problem for him. Good move by Diaz to rake in the money if he can get it.
