I'm a fan of both Henderson and Fedor, would've like to see more of a war with Fedor winning, mostly because Henderson couldve survived the loss more than Fedor could. Henderson loses, oh well, he got beat by Fedor, a heavyweight. Fedor loses, it's 3 in a row and to a LHW at that.
I do think the stop was justified. When herb goes in to stop it, it's at the moment that Fedor is flash KO'd, by the time Fedor came to (after 2-3 shots) it was too late, Herb was already stopping it. At that time, you can't just say nevermind keep fighting. On that same note, he can't look at him and not stop it, what if Fedor had been completely out, at what point to you stop them from getting hit too many times... Good call imo, sucks that it coulda gone on, but what can ya do.
