I'm pretty sure owners don't interfere with contracts, negotiations, signings, etc. Sure, owners and GMs meet to set budgetary limits and of course owners sign their names to the contracts -- it's their money, after all -- but it's the GM who makes the personnel decisions of who they sign and for how much. Weird as it seems, Molson must still have trust in Bergevin to make the right moves. To a point. No owner will publicly rip their GM, but there is absolutely a clock ticking down on Molson's patience and Bergevin's employment. He'll be fired eventually, but none of us will see it coming.
Molson is not only the owner, he's the President and chief executive officer.
Pretty sure he's involved in everything regarding contracts, trades and so on.
All those trades/signings made by Bergevin were approved by Molson!
Him firing Bergevin would be like firing himself at this point.
