San Jose just aquired Liljegren. We can probably snag Jan Rutta for a 3rd or 4th rounder. He's an upgrade but not an ideal one.
I'd bet that they would want a 2nd for Ceci or Rutta right now. They can always get a 3rd or 4th at the deadline with the benefit of using them until then to eat up minutes.
Celebrini is hurt right now, but I don't think they want to be a team who gets shelled every night. They have Celebrini, Smith, and a few other young stars to form a core. They need to start learning how to be competitive at an NHL level.
If they like JBD and he goes the other way, maybe that changes the dynamic because they are getting a young top 6 defenseman to replace Rutta, but if we are trading to replace holes caused by injuries, including JBD seems unlikely.
