I re-wound just to watch where Dean was when the KO happened. Remembering that he was really watching for finger pokes etc he's trying, as a ref always does or should do, to get position to see everything.
Dean was on the 'near'(right) side for tv within 2 steps but unfortunately for Blaydes Dean had swung over to the 'far' (left) side. Though Dean seemed 'set' pretty quickly after he'd circled to the other side, Blaydes shot in and Lewis threw the uppercut maybe a second after Dean had switched sides. Dean got in there pretty quickly but it happened fast.... I can't really fault Dean there and I'm neither criticizing nor sticking up for him. On the side he swung too, he might've been a bit further away from the fighters than on his original side but he was still close, and I think got there as fast as he could. It happened very quickly, that uppercut and the 2 blows. Maybe except for diving in there, which I don't think he could do because of the angle he came from, I think he did his best to basically jump on top of Blaydes to block Lewis from punching anymore. If he'd been behind Lewis he maybe could've tried to grab his right (but you can't ref a fight from a back angle, has to be side) but since he had to come from the side he couldn't stop those 2 sledgehammer blows, even the last one.
Interesting to hear that Lewis in his post-fight interview first said he didn't felt like he warmed up good. Then said that punch was his whole fight strategy. He knew Blaydes would shoot in on him and said he knew he'd land either that uppercut or a knee. Said he didn't care about 1-2 punch or anything else, that punch on a shoot was his strategy. Eventually said Stipe when pressed about who he'd like to fight next, though he had mentioned Jones' moving up to HW but something about not fighting for the title (his way of saying maybe he could? hint hint)
Brutal KO though, just wow. Should re-watch once more to see if my Dean description is accurate lol.
2nd re-watch: Dean seemed totally out-of-sight from the camera when the uppercut landed, looks like he had to run 2 or 3 good steps to get in there and stop it. Don't think he was too far away as those are big guys scrapping and some distance has to be kept.
