I think Grier's trades have been fine. If you have the two choices in the poll as "Supreme Thievery" vs. "Not surpeme thievery", I think you would get more "not" votes. The overall trade grade ranning seems in the B/B+ range. Good deals overall, not necessarily max return.
It's hard to argue for complete dogshit, but its also hard to argue for epic thievery. He has also gotten a little lucky as Pit missed the POs with EK (if that pick was 25 instead of 14, that deal would be less attractive), Dick fell in the draft. He also got very lucky that EK gave him a norris year, but good on Grier to sell high.
While selling his high end players on big $ deals has been respectable, building a historically bad team is not exactly a great skill. Any GM can build the worst team in the league.
The real test will be building a winner and relatively quickly. Any GM could do that with a decade of tanking and 7 or 8 top 5 picks. The real skill is building a winner relatively quickly, and not being mired near the bottom for a decade.
To do that, he is going to need to acquire lots of future capital very fast (check as he took a bottom 10 farm and made it arguably #1 in two years), draft well (check, not Celly which is easy, but Musty, dick, and others), trade well to bring in good players (a little with Zetterlund and maybe Mukh, but not much yet), and sign UFA's wisely (Toffoli perhaps? and perhaps a little soon to really make plays for the top names). In this regard, of course he is not there yet. Obviously, its too early in the rebuild to judge him too much on this, but his imports to date have been quite poor, albeit with minimal damage.
Quinn was a terrible hire. Lindbom, kunin (why is he still here?), Sturm, G Smith, Wennberg (TBD), Goodrow (TBD), Nuutivara, Benning, Zadina... While none of those guys is hamstringing the team with $ and term (goodrow a bit), its also true that none were any good.
The big question is can grier trade FOR good players and UFA sign good vets to build a team. He did trade for zetterlund which looks like a great move right now, mukh (TBD), and signed Toffoli, so perhaps the process of Building, rather than tearing down, has begun.
The next two years will really tell the tale on Grier's skills. If the sharks remain dead last and grier's additions flounder, then yes we would get two more elite prospects, but I think fans (and I) would like to see a quality product alot sooner than 2028, and I think deft adds would allow that to happen.
