I think the Kane signing and the potential Cap issues rule out both Kovy and Tavares. If they take care of what they have, they're pretty close with maybe some tweaks.
If Kovy really was a binary choice between San Jose and Los Angeles and I'm the Sharks, I let the Kings take them. In fact, if I really hate the Kings I suggest them to Kovy. Some of that is obviously based on my dislike of the guy, but at 35 I'm not interested in the price tag. The Sharks don't need him.
