The announcers on Saturday discussed this--the inverted screen.
As they discussed, this seems very hard to defend, partially because the guards defending Kam and Tyler aren't used to defending that side of the action (picking up Oso), especially when he has a head of steam moving downhill in the lane.
That said, it does seem like it is often technically a moving screen the way they run it. But, it seems harder for refs to pick up on it, since they also aren't used to seeing this type of action from a 5/1 or 5/2. I also wonder if it is harder to call because the screen is usually in/near the lane, where it seems more like bodies getting jumbled together instead of an intended screen--most moving screens involve a big out on the perimeter sticking out a hip/shoulder/elbow, so this just looks different than what they are usually calling.
Any rules experts that can weigh in? Is it definitely a foul? Even if it is, until they start calling it, I think it is a great play that they should use in key situations. That said, I think it is something you may only be able to get away with once or twice a game before the refs/opposing coach starts catching on.
