It's up to Wideman. If he keeps playing like he did the first 2 games, he's probably a candidate to hit the waiver wire. Personally I think you keep him on the 3rd pairing, at about 14-15 min a night and give him PP time, and I think he can be useful in that role.
Wotherspoon has never asserted himself in his entire pro career. Part of me thinks if he were given the ball and some trust, he would flourish playing in the more structured NHL. He can skate well, is solid positionally and can pass out of his zone. Game has no glaring weaknesses, but he has no glaring strengths either. I personally think both Kulak and probably Culkin are better players, but this season is Spoons last chance with us, of that I have no doubts. Kylington and Kulak will likely be on the roster full time next season and Andersson will be pushing as well.
