In the NFL it had been a truism for many years that West coast teams have a harder time travelling East when compared to East coast teams travelling West. Random study I googled for proof: NFL, NBA, and NHL teams have a disadvantage when traveling west: Evening games show greatest disadvantage for teams traveling westward I was wondering if there are any historical relationships that may be examples of this (Usually you need to cross time zones for this to kick in, so something like Pittsburgh to Philadelphia doesn't count.) What are otherwise strong West coast teams that struggled going to the East? Or perhaps players? (Are non-geographic matchups with Eastern Time Zone teams part of why Dionne was a playoff bust?) What are East Coast teams that excelled with Western visitors? Did Detroit have more of an advantage in the West, with so many in-Conference opponents travelling East to meet them?
