For what it's worth I think the whole language debate is pointless at best and a cop-out at worst.
People keep going on about "the most competent candidate" as if there was a shelf stacked with exceptional candidates that the Habs are ignoring. The reality is that the overwhelming majority of management and coaching personalities in the NHL are mediocre and the Habs limiting themselves to hiring only from a smaller wing in that gallery of mediocrity does not really have any negative effect. People who are truly exceptional are almost never available and in the rare cases that they are I have no doubt that the team would try to hire them if they could.
If you are going to hire somebody who is mediocre, which is what basically every NHL team ends up doing when they make a change, you may as well hire someone who is mediocre and bilingual.
We had an exceptional bilingual candidate in house in Julien Brisebois, they were available because we let them go since we were too dumb to move on to him when it was apparent he should be the successor.
And while yes, the majority of executives are mediocre and suffer from a similar problem (ex hockey players who get thrust up the corporate ladder due to relationships and not ability); you aren't noting one big difference.
The fact our bilingual pool is almost uniquely coming up through the QMJHL and Hockey-Quebec. Meaning that we are constantly hiring from the same philosophies and people coming up with the same ideologies. Learning the game the same way and applying those same tenants.
It's not a coincidence that if you blurred out the face of the coach behind the bench that you wouldn't find huge differences between Vigneault, Therrien, Julien and Martin.
