With me being a Dolphins fan, every time my friends (or mum) see Jax in teal/white they go "oh your teams playing" . Yes this is a small sample and yes i might have the dumbest friends in the world, but you know...
Im not saying every team needs to do that, obviously. But Jacksonville seems to have a bigger interest in Europe than most of the other franchises , and they also play basically every year in the Old Continent (remember when someone even said the might wanna consider the idea of relocating and becoming the "London Jaguars" ?). Dolphins are very big here due to their history (Shula, Marino) and city's background notoriety (everybody'll tell you Miami's in FLA, not a lotta people even know Jacksonville exists), so if the Jags want to appeal to the EU market they ought to distinguish themselves more, mainly by using colors no other franchise uses for merchandising and uni's IMO. Teal and black? yes. Teal and white? already taken .
Why isn't anyone selling Portland Trailblazers stuff here ? Cause there's already a team with richer history and the same color scheme (Chicago, obv) that's outselling them by a mile. But the Hornets are big in our market, and guess what, they got unique colors.It's not rocket science.
This is just my thought , but then, i aint no franchise GM nor marketing guru.
