Wait, the guy who's an analyst on RDS? If we could put up a defensive wall as stationary as his hair, we'd be unstoppable.
I really don't think that the bilingual requisite extends in any way to assistant coaches. They don't have to address the media, and most of the players they have to communicate with will know some English, and the few who do not know English likely won't know French either (young Euro players). An asset for sure, but not necessary.
However, the closest he's came to coaching is holding McDonalds hockey camps for pee-wee players. He could be a good coach in the future, but let him gain experience before throwing his name out there, even only as a defense coach.
