I feel like Montreal are the slightly least mediocre team among a bunch of mediocre at best teams. I think Maas has done a good job there, but I think their results are more a product of their competition than any sort of GM mastery from Maciocia.
Only team in the league that I would describe as "really good" is Winnipeg. Everyone else that is anywhere near a playoff threat are 5/10 teams at best IMO.
I generally agree with this, that they are a mediocre team, but Maas has shown an ability even dating back to his last season in Edmonton where his team shows up and gets the win almost every single time that they are even or favored.
Until this year, he hadn't lost a game since 2018 where the opponent finished behind his team in the standings, and it only really stopped this year because his team was first place all year but even then he only lost games to playoff teams, and most of the losses came once they already had a playoff spot virtually clinched.
Basically to this point, I feel pretty confident saying that as long as you have a GM capable of assembling talent that's at least close to average, Maas will get you to a Divisional Final. Also of note, he has also never lost a semi-final game as a coach.
