He'll have a job.
The hardest job for any GM, proven time and time again, is coming out of a rebuild/scorched earth.... he hasn't even started that ascension yet.
It's easy to demolish a roster, have 50 point seasons and draft high... the hard part is putting together the pieces to get yourself out of that cycle. That's what separates the teams that end up in the infinity loop of rebuilding/retooling and those that go on to become contenders.
He doesn't have to make the playoffs next year, but you'd want to see some small-step improvements from being a sub 60 point team. If he can get the team into the 35-38 win area that would be a big success in my opinion. My fear is that San Jose is going to be stuck in neutral for a long time; they sell everything not nailed down, and while that looks good on paper, it's hard to make the next steps when any veteran worth a pick is shipped out.
That defensive group will be the limitation on them doing anything. That's a dumpster fire if I've ever seen one.
