I totally get what you mean as far as enjoying playoff hockey and how dreadful watching the kings are right now. However, the Blue Jackets are 1 point out of the last wildcard spot, its one thing to add pieces when you are at the top or middle of the pack but they are at the bottom (Actually not even IN the playoffs right now) of the pack. I don't think losing first round picks, or prospects like Thomas, JAD, Clague etc... are worth it to see 4-8 playoff games. Those types of moves have a disastrous impact on the future of the team.
Now... if they go all in and Win, or even go all in and have an amazing ride to the finals or even make a hell of a series out of the conference finals, then I can see how it might be worth it for a little taste of glory for the fans, and watching the young players grow but that is a really risky move.
