Why would the Rangers-Astros rivalry make sense when all other states with 2 major somewhat local teams are located in different leagues? Of course, I long ago advocated a much more radical shift based on geography, but it messes with the AL/NL thing and most of us like having one league with a DH and one with the P: 1) NY, NY, BOS, PHIL 2) FLA, TB, ATL, Nashville?? 3) Pitt, Balt, Tor, Wash 4 and 5 (tough to arrange) Chic, Chic, Clev, Cinc, Mil, Minn, St. Louis 6) AZ, SD, LA, Ana 7) Oak, Sea, SF, Portland/Las Vegas/Salt Lake City/Calgary/Vancouver 8) Tex, Hou, Col, KC The Blue Ribbon panel from years ago actually promoted expansion, but they said the top 3 markets primed for new teams are: 1) new york, 2) new york, and 3) LA. Cities that might be able to support MLB based on other pro sports franchises or simply their size include: Nashville, Memphis, San Antonio, Las Vegas, Portland, Indianapolis, Boston, New York, and the Canadian Cities (thanks to a stronger Canadian dollar and them having perhaps the best performing economy right now...As we all see, Canadians are buying up tons of available land and homes in the US, at least where I go in Arizona and Montana)
