Pac 12 has said Stave did in fact take a knee, that the situation was totally fucked and has reprimanded and sanctioned the officials involved.
Not good enough. Sorry, but that crew should be suspended. Not once did they even attempt to explain that last 15 seconds of the game. Instead they botched the call, called it a day, and ran off the field like a bunch of gutless cowards with their tails between their legs. No sympathy at all when you don't even attempt to make a proper ruling.
