Do offensive & D-fensive quickplays only last one play?

I just wondered if you call an offensive or defensive quickplay, will your team only run that play one time and then go back into the normal offense or defense the next time down the court, or does it keep running that play until you call another play?

defensive plays, no.

offense im not sure

If you call for def/off plays, they only last once and you have to call it again. You can set what def/off your team or cpu team to run everytime in Team Strategy under Strategy.
