It ain't brain surgery.

As long as they work within the confines of the play so they don't disrupt the overall play or whatever is being set up for later in the game.

And of course the QB is going to need to know where they are going. Otherwise that's going to be a problem that could lead to game-changing interceptions.

Run to the open spot works great in some situations and in pickup, but it is a little more nuanced that you make it sound.
