For all the flack she gets, Kim Winslow made a great stoppage there.
I know I have seen her officiate several fights now. I don't see that she is all that bad. She seems to do ok. I can't recall her doing anything Mazzagatti-esk. It does seem a bit dangerous if she has to jump in the middle of a couple of heavyweights like that. She doesn't seem to show any timidness about it, though.
