As I wrote about just yesterday, the Pittsburgh Steelers are not a team that has a lot of success when they are asked to play out on the west coast. That includes three consecutive losses to very bad Oakland Raiders teams going back to 2006, and including games as recently as 2012 and 2013.
It’s not just Oakland, and not just the Pacific time zone, either. They have historically struggled, compared to their average record, in the Pacific and Mountain time zones more than most teams have, and there isn’t really any great explanation for it that is unique to Pittsburgh.
