I didn't get a chance to catch this game, but folks on the Stanford board were saying the same after the UCLA and U$C games, especially the folks who were watching in person, where you can hear (and sometimes even *feel* if you're seated up close) the players hit the deck. I think there's a brewing consensus that the refs are letting way too much contact go uncalled this season, and as it has progressed players have realized they have the green light to keep pushing the Overton window (as it were) on physical play.
Lord knows I've been the loudest and most vocal critic of the Missy loose whistle style of ticky tacky foul calling, but wow, the refs seem to have gone too far in the other direction this season.
My suspicion is that Rueck is especially PO'd because OSU has always been susceptible to really physical teams, and after the Kennedy Brown injury, I can see why he'd be doubly concerned.
