The Zetterlund trade seems to be the only fumble so far (and can end up as a W if Ostapchuk emerges the way Grier wants him to). Aside from that, I don't think Grier has any 'bad' moves. He's restocked the cupboards, moved out all the bad contracts on the books except Vlasic, and they've got loads of capspace to surround Celbribi, Smith ,Eklund, Dickinson & Co with good quality vets. No bad vet acquisitions either.
They get a retention spot back next season with Burns coming off the books, and they'll get a decent return for Ferraro or can use their capspace to help facilitate a trade for more assets.
I'd be pissed if I'm a sharks fan, but would believe in the GMMG plan
