What a randomly weird take
Yeah. Nothing says the CBJ is a clown organization more than trading a guy because he's "damaged goods" emotionally without ever getting a chance to cope with it and move on. In the Espen Knutsen example, his actions, albeit completely an accident, directly caused the girl's death. Dany Heatley's actions directly caused Dan Snyder's death. They both had huge amounts of guilt because of that direct connection. Elvis just happened to be there and nothing has been reported that anything he did was a direct cause.
I think Elvis can come through this. Allow him to grieve and refocus. This is what Kivi would have wanted him to do. Elvis is a guy who wears his emotion on his sleeve and I think in this case it is good for him. He can openly talk and express what he is feeling instead of keeping it bottled up. He is already doing some of that on his IG page with his tributes and appreciation for the support.
If anything I'm more concerned about Manny Legace and his family. It was his house. He possibly and probably purchased the fireworks for his celebration of his daughter's marriage. He could really harbor some long term guilt over this if not properly dealt with.
