I wouldn't bother giving any of the current UFA defenseman term based on Larsson leaving. It's a weak market with aging mediocre options. A guy like Savard will still likely be overpaid and over-termed.
I sign Barrie, because you need Nurse to go all Norris again. But I think you might be better off just signing a guy like Danault as the 3C and running with the suspect D unit in the short term until you can afford address it.
it doesn’t have to be Savard though. I was more upset about losing Barrie than Larsson, because Larsson is easier to replace. I’d rather have Larsson too, but you talk to Savard, Goligoski, Hjalmarsson, Edler, Murray, Demers, McCabe, Martinez, etc and see who you can get for shorter term at a reasonable cap hit.
