You have disappointed me grasshopper.

When the official is ready and until the ball is tossed, nonjumpers shall not change position around the center restraining circle.

There may be more.

The jumpers are quite easy to deal with.

It's the nonjumpers that have complex limitations.

And keep in mind that you have to process, interpret, and enforce, all these rules within the fraction of a second that it takes for a jump ball.
