[Ref in PA]

In two man, as the lead, yes I have switched sides and have had a couple of partners switch sides. This was only done when all 5 offensive players were on one side of the court and the play seemed to be developing in that congested area. I have only done it twice in my career, it does not happen that often.

As far as the trail switching sides, if there is time, the trail would switch sides, but if the ball begins going the other way, the new lead (old trail) usually stays on his side of the court and the new trail (old lead) would switch sides as he follows the play up the court.

This was taught in our chapter last year, it may be a PA mechanic only. Consult your local interpreter.
