The only way out of this mess is for the team to approach Hoffman and Sarah Silverman his fiancée.
If the allegations are true, I doubt his fiancée is evil. I doubt she is completely insane.

However, she must be in a lot of pain to lash out like that. She must have some form of depression or affect that has engulfed her mood. IF the team could convince her to seek help, make reparations, ask for forgiveness, this whole issue could be turned into a good thing. It could be turned into a prototype case for dealing with cyber-bullying behaviour.
You can't discard people. People make mistakes. I'd rather see this young woman get some help and clarity in her life rather than the team just move the problem along by trading Hoffman. The Sens have an opportunity here to really get ahead of this and be a leader on the issue. They have two players that are hurting right now.
The answer shouldn't be 'how much can the team get for a damaged asset?'.
The answer should be 'we have two incredible talents. How do we help this young woman get help and bring the Karlssons some peace?' You have four young, healthy, talented people that are now all hurting. Show some leadership and get some professional help for them.
