Not much can be added to that but there are some rare things happening.
Al Arbour came here in 1974 with nothing close to Barry Trotz current resume so it makes it a must-watch camp for every fan. Torrey was not where Lamoriello was in 1972 so very high management expectations.
It's tough with Lee, Eberle, Nelson on UFA years, but almost all teams have this issue, and if they are in a playoff spot those players will need to be retained, even at the cost of losing them for nothing.
Some players will regress, some will step up (hopefully Kovar or some prospects) the players Lamoriello added created a numbers game where NHL players will not make this roster unless there are trades/injuries.
