I'm going to make alternative trade prediction:
I think Yzerman is trading for an aging, proven veteran leader to add to the team and is giving them an 'A' immediately. I think this will be a top priority for the offseason and kind of end up being 'panned' as a move because it will be a "why is Stevie adding another washed up vet?' kind of vibe to it but it's done expressly to reset the locker room culture and to help out Mo + Ray, etc.
It's going to be at the high end a guy like a O'Reily, Stamkos, or Schenn (don't scream, I'm using then as an example). Someone whose a Captain or A level leader whose know for being hardworking, great locker room leader, veteran whose gone deep or won it all, etc. but definitely someone that commands respect, etc.
