I think there's a chance he could bounce back in the right situation. He's obviously not built to be the go-to guy on a team and not a leader. If Vancouver retains a bit of money (they would need to with their reported asking price, 1st round pick + top 2 center + another asset) and a team slotted him on their second line maybe he finds his offense again. Detroit has a handful of Swedish guys that might make him feel comfortable, and vets who can handle leadership and the media. It is no doubt risky as hell and not ideally what I would want to do. It's just tough to acquire high end talent and if they can somehow use his current play/slump to make it happen I think I'd be for the swing at a first, danielson and another mid prospect.
He also has a NMC so it'll be interesting to see if anything even comes of it. Plus Seravalli is wrong A LOT
