I don't know if I agree with that but I'm pretty sure I know why you have that opinion. Had a play in camp this summer in which I was the Lead on a fast break. Crash was just above the opposite block but all I could see was the defender's back from my 'pinched down' position. I had no whistle and the 'C' took the play and called a PC. NBA ref/college supervisor told his observer I should have had a whistle. Observer (big dawg D1 official) disagreed with his boss and said I rightfully let the C take it b/c I was straight-lined and the play was on the opposite side of the paint.
