I was reading an unrelated thread on ORG and got to thinking.
The distances between the NL central cities seems like it would be much less, on average, than any other division. With Houston leaving the picture, it's even smaller. The closest I could think of would be AL Central, but I think they have some further trips. Players could drive and make it to most cities in 4-6 hours. (Chapman in 2-3 hours )
During division play in the AL East, you might be heading from Tampa to Toronto if the schedule is unfavorable. In the NL Central, Pittsburgh to Chicago is a nap and a soda.
Does this even matter? It seems to me like it would, even if slightly.
