When a block is a foul

The rule of thumb is:
1) coaches and players think that it's a foul any time an opponent gets any part of the ball, whether there's any subsequent contact or not after that.
2) coaches and players think that it's a good block if they get any part of the ball any time on an opponent's shot, no matter what what the subsequent contact may be.

And that's why we never listen to the coaches or players when they start to whine about the above.

Just make the call and move on.
