Designated Free Throw Spot

[cford]

I saw this in a game on tv (a week ago?) and it got me thinking. When the players were lining up for the free throw, the bottom players (defense) switched so they could be next to the rebounder that they wanted. Then the offensive team players switched, which then caused the defensive players to switch. This went on 3 or 4 times until the official stepped in and put a stop to it.

My question: Logically I would think that the offensive players would be given first choice and then the defensive players the last choice. I don't have my book so I was hoping someone would know.
