For IAABO Eyes Only ...

Yes. Page 67, Graphic Narrative- New for 2020-21
Manual: Throw-In/Transition Fast Break To Frontcourt Sideline: During fast break situation, ball out-of-bounds on new Lead’s sideline, in the front court, above free throw line extended. The Lead administers the throw-in as new Trail, Trail becomes new Lead.

IAABO (and I believe NFHS) used to do this back when the lead had the entire sideline (didn't stop at the free throw line extended, actually extended all the way into the backcourt) as his boundary responsibility, not only in fast break situations but even in a half court set.

I remember doing this when the old trail called a backcourt violation on his sideline and I, as the new lead, would sprint (back prearthritis, pretorn meniscus, prebone spurs, when I could actually sprint) the length of the court.

I thought that IAABO did away with this “long switch” for good reason.

Seems it would be easier for the old lead to cross the basket line into the frontcourt to administer the sideline throwin and for the old trail to cross the basket line to become the new lead, thus fulfilling the creed of “only switch on a foul”.

While preparing to teach my local board's mechanics training sessions, I discovered that this trail initiated frontcourt rotation was was done away with after only appearing in the IAABO mechanics manual for a single year (2016-17).



When pressure is applied in the frontcourt, near farther sideline in Trail’s PCA, Trail may rotate beyond the basketline toward or to farther sideline to provide the maximum coverage. As a result of Trail rotating, Lead may rotate across the basketline, changing the Lead’s new PCA, field of vision cone, and line responsibility.

I never actually did this, but it would have been nice if somebody told me that the mechanic was changed after existing for only one year. I don't know who to blame, IAABO International, or my state, or local board, for not announcing the change. Of course it's also my fault for not reading the entire manual every single year (as I've been advised to do to prevent not being aware of things like this) and for me assuming that if mechanics changes weren't announced that there were no mechanics changes.
