Dillon - at $3.3m in annual cap hit for a bottom pairing, and not a notable one in the NHL, I don't think there's much to get from a trade unless the Sharks take back some of the salary.
Pavs & Cooch - The M-NTC clause restricting any trade to three acceptable teams is going to limit a trade as well. Best bet is this year at the TDL, and hope for an acceptable team that is in need for playoffs. Otherwise, I don't see much trade value considering the 29-team veto power these two have will be carried over to their new team, and then it's just for one full season before UFA. If it is an off-season trade, it will have to be contingent on contract renegotiation.... more $$$ and less coming back in the trade. The window is closing on trading these two much like it did on Thornton and Marleau.
Jones - if he continues to have an average at best season, one would have to think DW will entertain trade offers. If so, Sharks would have been better off sticking with Riemer and save about $2.3m annual cap hit. The flip side of this is whether the Sharks have acceptable goalies in the pipeline. Not having any, and wasting resources on Stalock's development is what got them in to this position.
The only guys DW can get a 1st round draft choice for are Burns and Vlasic, if they agree due to M-NTC and NTC clauses. Even still, I doubt it will be a high draft choice, unless the team has traded for an additional 1st round from a bottom-dweller.
Next up for tradeable players are guys that probably should not be traded if rebuilding, the youth core like Hertl, Meier, Labanc, Donskoi, and a few others. However, I don't foresee any of those bringing in a 1st round pick.
DW is not in a good position at all, with the exception of still have $5m in the cap limit. But if it's rebuilding, that probably doesn't help much unless it's used for retaining salary for better youthful players and draft picks. This is largely DW's fault because he likes to trade away a bit of the future to go for it at the time. Keep doing this, the roosters come home to roost.
Overall, tanking in a good draft year is the way to go. Worked well for Toronto, Chicago, Pittsburg, and Edmonton (although they tanked often and they don't run the risk of losing STH like Sharks do).
