Thanks in Advance

everything from past seasons that is kept is in the archive in the top row, so I don't think you can view depth charts from past seasons. You can view past season's rosters though on hockey reference (.com), and if you go to the team you want you can go back seasons and see players, numbers, and stats from that season

for example 18-19 habs: https://www.hockey-reference.com/teams/MTL/2019.html
