In the last decade or so, the more informed citizens of the world have made attempts to adopt an Eco-friendly mentality to help quell the effects of global warming. I believe major sports must do the same. I believe Major League Baseball is the least environmentally friendly of the major sports leagues with their Eastern, Central and Western divisions in both the American and National Leagues.
One of the best things about the NBA and the NHL is that teams are organized geographically, having divisions within Eastern and Western conferences.
Personally, I don’t think MLB officials would consider realigning to East and West out of both stubbornness and deference to the history of the National and American leagues.
But what about the “Original Six” of the NHL? They are in separate leagues, aren't they?
As for the NFL, I think they are due for an overhaul, a realignment that would preserve traditional rivalries while sparking new ones. This could all be accomplished while reducing the costs teams waste going cross country or farther than they would need to if they were organized more geographically (think “Cowboys in NFC East? Say what?” or “Why is a team from South Beach in the same division as teams from the Northeast?).
I have reorganized teams from the National Football League into geographically-conscious divisions. I have kept the names NFC and AFC and have applied these names to the conferences retaining the most teams from the current configuration. For example, my proposed NFC has nine teams who belong in that league and only seven from the AFC; the same goes for my proposed AFC, with nine original AFC teams and seven NFC teams.
