What would you tell this coach

[canuckrefguy]

The way the play is described, the hand contact sounds like a reactionary touch.....and did not affect the play.

If it starts to impede or is about to escalate, I'm dealing with it - "hands" and then a foul if necessary.

As much as coaches whine about supposed "handchecks" - one thing they all absolutely hate, without exception, is a ticky tack handcheck call.

Tommy,
The coach did not ask you a question. He made a statement. His statement was quite likely untrue. Coaches usually do that.
My best advice is to ignore statements, but answer questions while being as brief as possible.
Trying to explain the nuances of the rules to coaches is pointless. The majority of them don't care about the rules. They only want to get calls for their team. That is their job. Don't ever forget that.

Just call the game as you believe that it should be called and the players will adjust.
