In addition to the coaching, the roster construction is just horrible.
We lost Fast, one of the few forwards who can effectively PK and forecheck - did they even make an effort to find a replacement for him? There are far too many one dimensional skill type players and not enough that can play in all 3 zones.
Also, when you have a really young team, it helps to have a few solid veteran leaders in the locker room. The rebuilding Pens had Gonchar and Gary Roberts, the Kings had Ryan Smyth, etc. I guess our elder statesmen is Jack Johnson, not gonna cut it by any stretch.
