I mean yeah that goes for anyone. The whole team outside of a few have been underwhelming in terms of goal scoring, McMann included. Doesn't mean he's now fodder though. Even if he's not scoring, he's been hitting and involved as a depth player.
If Marner does walk, Domi becomes a top 6 RW for me. Chuck Kampf for anything you can get. Jarnkrok Im 50/50 on but just dump him too. This is how I see the holes in terms of depth chart (not really line combinations). Ideally you push down Holmberg to a depth/winger role.
