Why not acknowledge a coach

[ref18]

I will always try to respond to a coach when asked politely and respectfully a question. If it's a comment, I'm running right by you, if you're asking a question like, "what the hell was that??" I'm not answering you, I may even give you a warning.

Now having said that, sometimes it is not possible to stop and talk because play is going on, but if you approach me during a dead ball, I will try and make time to explain a call.

One more exception to this, if a coach is constantly asking me for clarifications, I will tell him that I think I have explained enough of my calls, and because this is slowing down the game will not be explaining anything else.
