This^^^^ When was the last time you saw Kovy fired up. After a hard game win interview on the ice. Locker room interview its just answering questions no big expression or excitement. NO BIG DEAL
I work with a Russian women who's answers are very short and to the point. Nicest person in the world, but you never expect her to act excited.
