It's impossible to truly know at this time, but I'd give Shero a solid B+. Like the Zacha pick and the trade for Palmieri. Seemed to go for skill and speed over size with the later round picks. The Blackwood pick was a head scratcher, but he did move down and pickup an extra 3rd next year so that's a bit of a plus.
I just hope they don't rush Zacha into the NHL. If he's ready, I'm fine with it. But he shouldn't be up here just because this team is terrible. He needs to develop appropriately, something this organization has largely failed to do with its prospects over the last decade.
