Lam too emotional?

To clarify.
As I said originally, I don't mind how he reacts in the stands where he spends his time but if all he does is to react with gestures, head-shaking and the like and not actually communicate, then is that enough from a coach who is supposed to be able to influence the team both before and during the match?
If everyone's happy with that, then that's OK.

How do you know he doesn't communicate to the team during the game?
