Big picture? This New York Mets “True New Yorker” thing is just outreach, marketing, fan service and the like. It’s a different spin than we’ve seen before, but it’s basically just “Nattitude” or “Red Sox Nation” or any other number of fan slogans/campaigns we’ve seen in the past.
Small, petty, fun picture? The suggestion that “True New Yorkers” are Mets fans is probably gonna make Yankees fans really mad. And I’m sure that, at least in some way, that was fully intended.
