One of the most intriguing on-ice storylines for the Columbus Blue Jackets is the competition to be the 6th defenseman. Barring any major injuries, the top two defensive pairs will be Seth Jones–Zach Werenski and Markus Nutivaara–Ryan Murray.
After not re-signing Ian Cole though, the Jackets will look to one of three young defenseman to step up and play along side David Savard on the third pair.
The likely replacement will come down to either Dean Kukan, Gabriel Carlsson, or Scott Harrington.
