I say just average performance by Ryan, sure the power is there, but I think Davis has more power than Ryan. He doesn't have that head movement, he just keeps coming straight. And if he fight like that against Davis, who is very cerebral in the ring, for sure he will get knock out by that. It's a win though so no question about it, but it's just a so so performance and everyone expected that he should knock out Fortuna which he did.
I think under Goosen, he learns how to tuck his chin now and becoming more of a body puncher. The first punch was a fake head shot and then Fortuna covered upstair, so Ryan go down and hit him perfectly, so that's good if he can developed that and not head hunting first at least to throw his opponent in the beginning.
As for the Tank, Ryan said that he is no longer going back to 135 as well, so if there is a chance that a mega-fight between him and Davis happen, it will be in this weight limit now and it's up to his camp whether to accept it or force Ryan to 135 and drain him.
