I am guessing that a "Dubist" is some sort of Kyle Dubas fan boy who believes KD can do no wrong?
That's not me and maybe that's why I am not in the fetal position right now, but I was a Dubas supporter and believe he made a lot of good moves and that we will benefit from those this year.
Having said this, it was time for him to move on. I was glad that we did and I was concerned that Treliving was the next man in. Tre's first few moves, singing Klingberg and Reaves, concerned me.
We can get into a "who drafted the player (scout or gm) but I see the GMs role as assembling and retaining talent and Tre inherited a roster that included Matthews, Marner, Knies, Nylander, Tavares, Robertson, McMann, Kampf, Jarnkrok, Holmberg, Reilly, McCabe, Liljegren, Timmins, Woll, and Hildeby. That's a pretty solid core. Maybe the core four was making a collective $4M than we would like through the Dubas years, and more this year as we knew would happen in the final JT year but he kept the group together and if the cap hadn't gone flat and had $15M more on it we might not feel the slightest overpays as much. He also left us with Minten, Niemela, and Akhtyamov.
Tre definitely put his fingerprints on this team adding useful players with size and/or grit in Domi, Pacioretty, Lorentz, Reaves, Dewar, Tanev, OEL, Benoit, Hakanpaa, Myers, and Stolarz. He also added Cowan, Danford, and Webber to the prospect pool. We are in decent cap shape too and let's see what Tre does with Kampf, Jarnkrok and Liljegren, two of which were his (re)signings.
Of course, swapping Berube for Keefe has a big impact.
My point? At this point in time, when we are feeling good about our start and maybe even our prospects for the season it's easy to see the contribution both GMs have had and it seems as though Tre was the right guy to follow Dubas.
