Well considering the Habs had capitulated the season and were in full on tank mode, that list doesn't mean much.
Let's look at the names he inherited that you failed to mention.
Patches Price PK Markov Plex Beaulieu Tinordi, Gally 3rd overall pick. More than enough to build a core of players around wouldn't you say?
Jim Nill basically had Jamie Benn, Lehtonen, Loui Eriksson, Goligoski, Oleksiak, Chiasson, Dillon etc.
I'll take the Habs starting point over what the Stars has everyday of the week.
First, I can't believe we're actually having a conversation where were knocking a GM because he inherited certain players. As though when Bergevin started, he should of started out by waiving Price/Subban/Pacioretty
But to actually answer your question
When I look at both groups of players..>I don't see the big difference
Firstly, I don't even know why you're mentioning Beaulieu & Tinordi, neither is really established in the NHL.
Galchenyuk wasn't part of the organization when he took over either
I don't know what the purpose of this exercise is to be honest
