The 2017-2018 season will see “new” jersey designs for 12 NHL teams, including the Columbus Blue Jackets. Yesterday, Adidas released small previews of the jerseys in their #FormTheFuture campaign.
I say “new” because it appears as nothing has changed. There was discussions of the cannon being the primary logo, color scheme shifts, or a combination of the two. The tweet appears to take all of those changes off the table.
The bottom left quadrant of the flag and star logo appears in the tweet. The colors remain the same and there is no sign of a cannon.
