I'd be careful with this, coach. Sometimes, if they've been beat that badly, they're better off letting the shot get off.
That said, if you tell them to get the ball and that a foul is okay in this case, they're less likely to get an intentional foul called if they're trying to get the ball as opposed to simply trying to prevent the shot from going up.
The way you worded it, it almost looks like a "text-book" definition of an intentional foul.
