Ignoring the hyperbole from my fellow Sabres fan above......
It's become glaringly obvious that Olofsson's future likely isn't in Buffalo. He needs to be in a top 6 role with plenty of PP time to be an effective point producer.......and we just don't have the ice time for him.
Consider: Tage, Skinner, Tuch, Cozens, Peterka, Quinn are all currently above him in the "depth chart", and Mittlestadt is probably above him too. The Sabres WANT Krebs to be there.....and then next year we're bringing Savoie and maybe Kulich and maybe Rosen into the mix. The numbers game say his future isn't in Buffalo.
Also see above for Mittlestadt. Same reasoning, though Mittlestadt is showing signs that he could absolutely thrive if given decent wingers in a top 6 role.
