And then there's the AL East. Closest team to the Rays is Baltimore, at 967 driving miles based on Google Maps' shortest distance between the teams' stadiums. Everyone else is further north, New York Yankees, Boston Red Sox, and Toronto Blue Jays.
Believe it or not, Tampa(82° 27'W) is only 30-35 miles further east than Detroit (83° 02'W) and only 25-30 miles further east than Columbus (82° 59'W). Even though we are in Florida, we are very much riding the border of being in the West.
If we want to be really technical, Atlanta (84° 23'W) should be in the west as it is 50-60 miles further west than Detroit. Even more so relating to Columbus.
No need to be too technical, because it makes more sense for the teams to be grouped as they currently are. Having nearby teams in the same division creates more natural rivalries.
I think the NFL has it really messed up with all 3 Florida teams in separate divisions. (NFC South, AFC South, AFC East) Then again, preserving the Miami-Buffalo and Miami-NY Jet rivalry was probably important.
