from Tim Wharnsby of CBC,

...enough time (30 days) has elapsed to check in on the five teams that made the biggest moves at the NHL trade deadline.

Columbus Blue Jackets
Record since trade deadline: 7-7-1, 15 points in 15 games.

Situation: Columbus has six games remaining, and back-to-back shutout wins have pushed the Blue Jackets to two points behind the Canadiens for the final wild-card spot in the East. Columbus has a game in hand and owns the tiebreaker over Montreal with 41 regulation and overtime wins (ROW) compared to the Canadiens' 39. A key outing is slated for Thursday when the Habs visit Columbus.

The skinny: The Blue Jackets went all-in on this season when general manager Jarmo Kekalainen chose to keep pending unrestricted free agents Artemi Panarin and Sergei Bobrovsky. Columbus then shipped out more assets to supplement that core with forwards Matt Duchene and Ryan Dzingel, and defenceman Adam McQuaid. If John Tortorella's side fails to make the playoffs, the end result will knock this franchise back years, especially if their free agents walk. But Duchene, who has scored three goals and eight points in his 17 games with the Blue Jackets, has just as much pressure. He could be a difficult sell if he misses the playoffs for a sixth consecutive season.
