Comparing the ref's injury to Hayward's is way beyond apples and oranges... more like apples to freakin' planets! If it weren't for surrounding soft tissues, Gordon's foot might have come completely off. He was coming down off a running leap under the basket in traffic, not jogging up the sideline. You could hear the bone break on the audio. I won't post the video out of deference to people who just ate dinner.
Other than that, I agree with you 100%. These games are a big deal for the refs too, and I'm sure she only wanted to go out and call a great game. Probably never anticipated that something like that could happen. Hope she recovers quickly and completely.
