This isn't relevant to the enforcement of the play in question, but I thought I'd share this story from a game I had last year, to possibly shed some light on this "additional practice."
Boys 8th grade game...
I'm L in transition on a press break. A1 gets the ball and dribbles across half court and inside the 3-pt line to finish breaking the press. HC for A requests time out which my partner grants (I'm guessing the coach wanted the time out as soon as they crossed half court, but there was some delay in that communication).
A1 decides to take the final dribble and shoot, while B4 stands puts his hands up and steps in A1's path to stop him. A1 runs into B4 and is deflected to the side. All of this happened within a second or 2 following the whistle. In other words, I didn't think B4 explicitly sought contact or was acting unsportsmanlike.
A1 looks at me with a
face, like I should have called a foul. He says "But he didn't let me get my free shot."
I was kind of surprised by his response, because I was always taught to give the ball to the official... I'm assuming it comes from watching all those NBA games where guys shoot the ball after the whistle every time. Now players are assuming that they get a free shot after every whistle.
