My list of UFA forwards that fit the roster's biggest needs isn't the sexiest... but again, I think that the #1 priority should be stabilizing our historically bad PK. Here's a list of UFAs who scored 15+ goals last season and played significant PK time
Teuvo Teravainen
Jake Debrusk
Adam Henrique
Dakota Joshua
Elias Lindholm
Chandler Stephenson
These are realistically the guys we should be targeting IMO, with Teravainen, Debrusk, and Joshua being my favorite adds. Lou has history with Henrique and loves a vet, so he might be the most likely here. These aren't the sexiest names in FA, but they may be the ones that are best suited the help plug the holes in the ship.
It's also worth noting that Tsyplakov scored 4 SHG in the KHL last year. It's fully plausible he ends up with both PP and PK time next season.
