When is it legal to have more than one player OOB during an inbound play? I know it's a "T" to leave the court, unauthorized, but I've seen several inbound plays with two or three players OOB working to inbound the ball. I think it's only legal when team A can run the baseline, but not sure. More specifically, can I design a legal inbound play, after a dead ball, where the primary inbounder is at the official's designated throw in spot and also place a second or third player OOB as a misdirection, and then have those second or third players re-enter the court?
TIA,

You're right---it's only legal when A can run the baseline.

This is definitely a technical foul.

No, it's not. It's a violation.

No teammate of the thrower shall be out of bounds after a designated-spot throw-in begins.
