His presser today was a lot better, he explained his bad temper after the game and apologized for his behavior. I give him credit for that.
And as for why he apologized, I've watched most every presser he has done since he became HC, and I'd say that when he calms down he is a pretty decent person who believes in treating others the way he'd like to be treated, but the heat of the postgame and at times other instances seems to cause him to lose perspective or balance.
