That would be awful, especially with the 2018-19 version of Chara. I think you are right, the Bruins could survive and thrive without Krug, but he would be missed, and I'd rather they not move him out. It may come to it if Krug is the player than can bring a talented goal scorer in, or if his contract demands look a little high, though. Charlie, if he stays healthy, can do some of what Krug does, and Grizz some, but neither of them have quite the amazing offensive skill set and vision and hands that Krug does.
