Former general manager of the Canadiens, Marc Bergevin, did a good job in Montreal if you look at his overall work. So it wouldn't be surprising if he becomes GM of a team again someday.
In fact, it's about this that the rumors are intensifying. Bergevin is linked to Pittsburgh. It should be recalled that Ron Hextall was fired on April 14th. Now working with the Kings, Bergevin still has the ambition to become a GM again in the NHL.
