Delay of game?

[ma_ref]

I agree with the previous posts. No delay warning. No question (in my mind anyway) this is a T for unsportsmanlike behavior.

Once in a while during a dead ball you'll see a kid throw the ball to the wrong ref just because he/she genuinely did not see the other nearby official because (refs were switching/screened by other players/etc...).

Here you said the player clearly saw you...the same player who just had a call go against them...and had that look of anger/disbelief in their eyes. Go with the T. But if you still insist on the delay warning, then it should've been you blowing the whistle and issuing the warning, not your partner. Similar to when a coach is yelling at you for a call (or no-call), and your partner T's up the coach from across the floor, when in your mind, the coach hadn't quite stepped over the line just yet...
