Good point. I forgot about that. That's actually pretty insane. The whole time, Kris just had one week off. Still though, I've honestly never been that impressed with McCray other than the fact that he's pretty tough and can take a good punch. He's got crazy heart, and if he developed and polished his skills, I'm sure he could be a decent mid-tier guy in the Middleweight division.
I will leave my judgement on him to when hes had ample time to recover. Your are right about his heart you cant beat it.
