The bare minimum for Bergevin this off season is to fire the power play coach (Dan Lacroix), fire the Hamilton coach (Sylvain Lefebvre), and to either sign Petry or get someone else.
Aside from that, there are a lot of contracts this summer, and Bergevin will have to get good deals.
Unfortunately, each of Beaulieu, Galchenyuk, Pateryn, Tinordi can expect a two year deal, suggesting a few significant raises a few years down the line.
In 2 years, Markov, DD, Parenteau, Plekanec, Weise, Prust and Gilbert contracts are or have already hit UFA status..that's a lot of cap relief. I can only picture Weise and Prust sticking around, maybe Plekanec, but I see him more as trade bait
