15-17 Officials Manual "Bump and Run"

[Scratch85]

I received the new Officials manual today and for the most part, think it is an improvement over past years. However, the "bump and run" described in Diagram 5-15 is not how I have done it over the last 20 years.

5.2.E.3 If the ball goes out of bounds in the backcourt on Centers sideline and there is a change of possession, the Center will slide down court to administer the throw-in and become the new Trail. The old Trail will move to become the new Lead and the old Lead will move down court to become the new Center. See Diagram 5-15.

The diagram shows all players in the frontcourt. The ball goes out of bounds in the backcourt on the Center's side. The old Trail goes downcourt and crosses the endline to become the new Lead making the old Center the new Trail. The old Lead slides down to the new Center.

In my experience, the old Lead would bump the old Center to the new Lead and become the new Trail. The old Trail would become the new Center. How do you "bump and run" in this sitch? Have we been doing this differently than the rest of the world in my area?
