Blowing whistle...team losing advantage?

[jcurtin]

Another post got me thinking about a situation I haven't seen yet, but figure could likely occur.

The ball is live and Team B has possession in its' frontcourt. A1 steals the ball and has a wide open layup the other way. Before A1 shoots the layup, however, B2, husting down the court, blatantly shoves A2 in the back, causing him to fall.

I imagine the official would need to blow the whistle immediately, as to prevent any further escalation of the situation. But by blowing the whistle, wouldn't you be taking away a easy 2 for Team A, who could get two shots and the ball again - a potential 6 points in one trip?

I believe its a similar situation when a defensive player is injured in the backcourt and the other team has a breakaway the other way... you wouldn't blow the whistle until after the made basket or the defensive team gains possession, I believe.

Any thoughts?

Thanks,
