A.R. 223 With 30 seconds on the shot clock A throws the ball in and it is touched by A2 in the backcourt. The clock runs down and B1 knocks the ball out of bounds, now with 17 seconds on the shot clock. All 3 officials have missed a 10 second backcourt violation. This case play says that the out ob bounds violation by B must be penalized. My question is how long does team A have in the backcourt after the throw in? Is it an immediate violation when A touches the ball in the backcourt prior to the ball obtaining front court status?
