I have to agree with Dash and the other posters on the nervous thing.
From personal experience, being a Communications person, I arrange and see a lot of civil servants doing interviews for the local media, and some are naturals, while others continuously play with their hair, or stroke their chins/goatees, stutter, laugh nervously, etc...
I just chalk it up to nerves, and to be honest, besides Avery, who really relishes the cameras, and on another note, I want my players to be hockey players: tough, skilled, gritty and rarin' to go; not primping their hair and speaking oh so softly and eloquently. But hey, that's just me.
