Blowing the whistle coming in from a long delay (timeouts, injury, multiple subs, scorer's table issues) is the recognized mechanic by the Fed. Some guys that I have worked with in higher level games also blow the whistle on a baseline inbound staying in the frontcourt. I don't know if this is the official mechanic for NCAA/NBA, but when in rome....
