It'd be contingent on San Jose's primary target being somebody they think they could still land at #6. With this draft class, that seems unlikely since there seems to be a tier drop after #5. I think there's a bit of a misconception that a team would trade down if enough draft capital was offered. Handful of examples:
- 2006: Boston offered #5 and #37 to Washington for #4. When asked who'd they be taking, Boston said Nicklas Backstrom which was a no for Washington.
- 2007: St. Louis wanted Jakub Voracek and offered #9 and #24 to Edmonton for #6. There was a perceived tier drop after #7, so Edmonton declined.
- 2016: Columbus made an undisclosed offer to flip #3 and #2 because they wanted Patrik Laine. Winnipeg wasn't interested.
- 2017: Vegas wanted to make a splash to get Nolan Patrick. It would have been a two part trade where Vegas tried to move up from #6 to #3, but Dallas said no because of the perceived drop after Heiskanen/Makar. Darren Dreger also said the Rangers pitched #7 and #21 to Dallas for #3 but were declined.

Examples of when a trade did come to fruition:
- 1993: For better or worse, San Jose wanted Viktor Kozlov. So they traded #2 for #6, #45, #58, and Sergei Makarov (plus a conditional pick if Kozlov was off the board). They didn't do the trade because they were floored by what Hartford was offering. They did it because they would have taken Kozlov at #2, so now they could get Kozlov plus some extra assets.
- 1998: San Jose dealt #2 and #85 to Nashville for #3 and #29. Nashville wanted a forward to sell as the new face of the franchise. San Jose wanted a cornerstone D to pair with Patrick Marleau who had been picked the previous year.
- 1999: The overly complicated Brian Burke trades happened because Tampa/NYR and Atlanta happened to have different guys on top of their boards.
- 2002: Rick Dudley and Doug MacLean made an outside the box trade. Florida was going to take Jay Bouwmeester #1 but was able to move down to #3 and still get him.
- 2003: Panthers had Nathan Horton ranked #1 but figured they could move to #2 or #3 to get him. Dudley tried to drum up a trade market but ended up taking a relatively forgettable package to move to #3.

TL;DR - Unless the Sharks had somebody like Dvorsky/Benson/etc in the same class as Carlsson/Smith/Michkov, they'd probably decline. Or if there was a scenario where San Jose wanted say Michkov and they knew Arizona/Montreal wouldn't take him then maybe there'd be a deal to be had. It's just difficult to say that #4 is definitely equal to #6, #38, #70, next year's 2nd, etc.
