He might sit out, I would consider that if I were him. BA holds all the cards and can let Chych dangle in the wind forever. What good will that do? Maximize the return we all hope, but at what cost? We get a sideshow in preseason, reporters will be asking Chych, do you want to stay, when do you think you will be moved, then it continues into the season. The players all know he is getting moved and won't be here.
The rest of the NHL Gm's will understand why Chych would sit out, every GM has had a conversation with BA, they know Chych has been shopped for 9 months. Chych has played nice so far, sitting out will help force BA's hand.
