Yah, he has time, but it really depends on how Joe and Patty deal with the deadline this year. If DW doesn't add or sells, it's going to be made very clear to them that he isn't serious about winning right now, what will they do? If they stay, do we want them (because clearly winning isn't their top priority, etc)?
If DW adds at the deadline, and the Sharks fail again in the playoffs, does DW lose his job? If he doesn't, is even more pressure put on Thornton and Marleau than it was this off-season next off-season to waive? We know Thornton was pissed off about the whole thing, and about being stripped, that was made pretty clear, but how has that sat with him as the season has gone on? Does a new GM want rid of them from the outset? There are a lot of very realistic reasons either or both could still get moved.
The Sharks winning the cup is really the only easy answer to predict, but the least likely of outcomes.
As I've laid out before, I don't think Wilson will add at the deadline, I think that's just about as unlikely a scenario as a cup win. The team isn't performing well enough to even make it a tough decision for him. He's going to stand pat, or sell off parts as he has the last few seasons (Niemi at minimum, likely some mix of Kennedy, Sheppard, Brown, Desjardins, Scott, Hannen, Irwin). He's going to do that because I am fairly certain that last season Wilson stuck his neck out for a team that was performing well who then let him down in the worst way possible. I think it would be career suicide for him to do so again, and I think he already has a pre-approved plan to rebuild with Platner and is going to stick to it (for the sake of his job if nothing else). So what will Thornton or Marleau do? It will come down to where their priorities lie and whether Wilson commits to competing next season or not. If Wilson still has another rebuilding season planned I think Thornton probably waives, I think he wants a cup before he retires. Marleau is a bigger question mark. I think it's entirely conceivable he rides out his contract here and either re-signs for very little or retires early. That's all conjecture of course, but that's kind of what I expect.
