Until recently, before things began to trend upward in a positive direction for the Columbus Blue Jackets, there was quite a bit to dissect.
A porous power play — really, for nearly two full years now (30th, 15.9% since Jan. 1, 2016) — that started the season 1-for-1 and promptly fell to the bottom of the league until recently. A penalty kill that fell from ninth in 2016-17 (82.5%) to 27th (76.2%) last season, and has been in the lower-half of the league this season. Inconsistencies up and down the ice, injuries to Seth Jones and Brandon Dubinsky, bad goaltending by Sergei Bobrovsky (23 goals allowed in first six starts).
