Is "the patient whistle" and "possession consequence" ruining the game?

[just another ref]

With regard to a patient whistle, invariably the idea of waiting to see if the shot is good or not comes up. This, to me is not something that should ever happen. The contact on the shot must be judged on its own merit and the result is what it is. I am much more likely to hold the whistle for a player about to beat his man off the dribble. Defender is late with a bump or a grab. If the dribbler comes out clean and has a layup, let it go.
