IMO, Frk really didn't have a spot going forward.
Barring a trade or two, Larkin, Mantha, Zetterberg, Nyquist, Bertuzzi, AA, Abdelkader, Helm, Nielsen and Glendening are probably all everyday players when everyone's healthy. That leaves two regular spots open. Seems like one is a lock for Rasmussen, as they likely wouldn't keep him on the roster to be a healthy scratch. The other is probably for a UFA or Svechnikov, both of whom would also likely be regulars. Frk would've been sitting in the press box with Witkowski on most nights.
He didn't really produce enough at 5v5 to challenge for a spot in the top 9, and he isn't exactly the type you'd want on the 4th line. On top of that, his one ability on the PP got stale when the league figured it out about a month and a half in and he just kept doing the same thing.
