I don't know, how about west regional, south regional, east regional, etc,etc,etc.... isnt that what other sports do? also the defense of the system still doesn't explain how coastal was sent on the road. seems like they can use the system when it benefits them and not use it when it doesn't.
P.S. there seems to be too much "inside baseball" .... why not more transparency, reminds me of soccer coverage how the announcers seem to want to exclude certain "new fans" who they don't deem to be "true fans"... open the books, get rid of inside baseball tactics, publish the rules more prominently for all to see well in advance.... other examples - some stadiums couldn't play songs, then some could, some have to give tickets to visitors in prime section others don't, inconsistencies with uniforms, dugouts, locker rooms, you need lights to host but team was only scheduled day games anyhow when on road, etc,etc,etc....
