After defending his title against MM in 2011, Cruz didn't fight again until 2014. He fought 3 times in 2016 and hasn't fought since Neck Tatts embarrassed him over 3 years ago. Safe to say he never fights again? Cruz and Cain are the 2 fighters I think of most when it comes to what could have been if it wasn't for injuries. Shogun as well since his prime ended because of injuries but at least he continued on.
