Just watched it. It was moving. I feel like it was decently subtle though. Not surprised it wasn’t called even with the ref looking right at it.
Not sure whether or not they were switching. I don’t get why you wouldn’t be switching everything, but Matthews is trying superhard to fight through the screen, and Livers doesn’t seem to be playing defense at all like he should be switching (he doesn’t even seem to realize that his man is setting a screen).
