I don't get all the hub bub. Really, a patient whistle lets you see whether or not advantage has really been gained. I look to see if the shot was altered because of the contact, not whether the ball goes in or not. That said, I'd have a lot more "and one" fouls if I didn't have a patient whistle. This is where I could throw in the phrase "game interrupter" and some people on thread would have a stroke.
