I dunno.
Sharks are my #2 team so I have mixed feelings about Wilson.
I think their scouting has been great in terms of draft picks - I think Marleau, Pavelski, Couture and Vlasic are homegrown players (then there's Nieto, Hertl, Mueller, Tierney, etc.)
The Brent Burns trade was a home run, and the idea of making him a forward (McLellan?) was brilliant.
But many of Wilson's player additions are puzzling - guys like Mike Brown, John Scott.
Sharks have suffered through a series of goaltenders who were pretty great during the regular season but never got hot during the playoffs - Nabokov, Toskala, and now Niemi.
Their D was pretty solid at one time - but they've lost guys like Ehrhoff who they should have kept. Matt Carle, etc. They did get Dan Boyle, which was a great move. But once Boyle was gone, he didn't really upgrade the defence.
People talk about the Sharks choking against the Kings, and obviously they did, but Vlasic got hurt, and their D corps was terrible without him. And Niemi couldn't stop a puck.
Then Wilson says we're "kinda" rebuilding but not "rebuilding", yet does absolutely nothing to improve the team.
tl;dr - maybe Wilson just needs a change, but I'm not sure he'd be my 1st choice for GM. But over Mac T? Definitely.
