Quoting: GMBL
Honestly, looking back at his trades, I think he got more out of Duchene than he gave up, if you don't count Turris. Hindsight is 20/20 of course.
He did pretty good with the Karlsson and Pageau trades, but the Zibanejad and Stone trades haven't turned out well (so far).
They traded away Turris, Bowers (bust) but most importantly the 1st that led to the Avs taking Bowen Byram 4th overall in 2019.
When trading Duchene, they got 19th overall (Lassi Thomson), Davidsson (bust) and Abramov (Russia). Lassi's value is now closer to a late 2nd early 3rd if they're lucky.
They most definitely lost that trade.
EK trade worked out very well for them but I don't give Dorion too much credit there as no one expected the Sharks to fall off that quickly and gift them a franchise player in Stutzle at 3rd overall.
Stone and Zibanejad trades were trash.
He did very well in getting assets back for Brassard, but then traded Gus for an expiring UFA in Talbot and JBD is currently a 5/6/7 and at best will become a #4.
Dorion needs to go. His asset management is embarassing.
