If you looked at the clip of Igor's Nat'l team you'll see that the C rarely came out to set picks for the guys in the weave action, typically he came to top half of the key and received a pass there. One or more of the weavers sould cut by him, rather like a pinch post maneuver. I don't know why he doesn't have Ayton doing that - perhaps because Ayton isn't proficient enough to make it work yet. So we'll see it in good time.
Not many C's can work the pinch post because he has to have a deadly jumper from the elbow, and it does require good footwork and mobility. Ayton would be an ace at it once he had it all polished. The other four players have to have their roles down, too. To get the most out of it the players have to read and react, but it isn't that complicated. Done right all five offensive players have the potential for a lay up, depending on what the defense does at various stages. It's not the blender action Igor talks about, it's a sequence where one defender after another is put on the hot seat.
