So, if a brand of baseball were shared between Charlotte and Portland, I like the sound of the "Coastal King Coasters". They could even camp some regular season games in the likes of Sacramento; Monterrey, Mexico; Atlantic City, St. Petersburg, Jacksonville and New Orleans.
I see Travel-Tag Teams as a future in expansion for the likes of MLB, NBA and the NHL. Doubts about markets like Las Vegas could be lessened when there are more camps at stake.
For markets like Portland and Charlotte for as far as Major League Baseball is concerned, you're the closest on the cusp but not even on the cusp. Ditto for New Orleans and Nashville. The reincarnation of the Expos could be better served as the East Coast Expos or International Expos of Charlotte and Montreal Flights. Las Vegas-Montreal Internationals playing in Nevada and the Montreal-Las Vegas International Expos playing some days in Quebec has a bit of a ring to it, don't you think?
I've blogged about it. Click links below:
