A day after free agency opened, it's far too early to weigh the work of Marc Bergevin setting the roster up for next season, but over three years into Bergevin's tenure as general manager of the Montreal Canadiens, it's actually very surprising how much of the roster remains full of the products of the era of Bob Gainey and Pierre Gauthier.
To illustrate this, I've taken the Canadiens' organizational depth chart from EOTP, and coloured in each player orange if they were acquired either directly or indirectly (through draft picks acquired by that regime) by Gainey of Gauthier, and purple if they were brought in by Bergevin.
