The New York Red Bulls' 2017 season starts on February 22 with a CONCACAF Champions League quarterfinal match against Vancouver Whitecaps. The club has been aware of this for some time, and will presumably get around to cluing fans into its plans (preseason, ticket pricing for the big game, etc.) when it is good and ready to do so.
In the meantime, MLS has announced its 2017 regular season home openers, having barely concluded the 2016 playoffs and a full month of suggesting to fans the regular season is irrelevant.
