The Avs had to do something about their barren center position but this doesn't exactly strike fear in our hearts. The Preds took off when they promoted their AHL guys over Johansen and co.
For the bottom 6 I would bring back JFK, let Glendening walk (Or retire? Do other teams covet literally the worst offensive player in the league?). I'm always open to a Faksa trade and it's possible seeing him in the playoffs could lead other teams to overrate. There needs to be a larger philosophy correction de-emphasizing faceoffs and promoting speed/forechecking.
I have very little faith in Dellandrea's hockey sense or future development so I consider him a bottom 6 player until team control runs out. Kiviranta-Bäck-Dellandrea would be the type of 4th line I'd be trying to build. Fast, cheap, under 30. I've seen a decent amount of progression in Bäck. You still have the lefty/righty faceoff taking split with him and Dellandrea. That's a line that could possess the puck and get in on you.
