I'd say he's done well in trimming the fat on this team. A lot of dead weight has been shaved off, and it gave guys like Kempe and Iafallo more of an opportunity. I don't think he wanted to rush into making any regrettable decisions. Clearly he's not a GM at the level of a Steve Yzerman quite yet, but he's not sitting on his hands either.
I think from the get go one of the prime areas he wanted to address was stockpiling more prospects, and he has done so his first year in. I also wouldn't consider the offseason a failure if he fails to land John Tavares.
