You had to figure it was only a matter of time before this news was going to come out, or that the tweet would be leaked.
Since Adidas took over the NHL’s jersey rights (2017), not a single team wore an alternate sweater this past season (excluding outdoor games). Though, just like the Reebok Edge series in 2007, Adidas planned on unveiling third jerseys for teams in year two of its production, 2018-19.
There was a tweet sent out recently that pictured a “confidential” Adidas catalog, which displayed 19 blank jerseys for teams that were “confirmed” to be wearing alternate jerseys next season.
