I'm not even sure why they're so bad
They were forced to trade their number 1 center, but Tage Thompson immediately filled the void and developed into an impact center. They have, or rather had decent offensive support, and seem to be able to consistently find good players up front to the point they've become a feeder team of scorers for other teams in the NHL. They've got 3 defenseman almost any team in the league would want in their top 4, two of which look like franchise number 1 type Dman. They've even had good goaltending at times, and somehow pissed that away as well.
You would think that will all the coaches they run through there, they would have found at least one guy who could put something together that would result in at least a little bit of success.
