I stumbled across this link on a message board thanks to a grumpy 49ers fan (not TDC, but this might make him grumpy afterwards). Apparently San Francisco is going to be travelling the most out of any other by a quite large margin. That's what an away game in London will do to you. Thanks to the geographical isolation of West Coast teams, this seems to be pretty common every year. Take a look at the chart below.
The top 5 teams all reside on or near the West Coast, with the 6th team being Jacksonville, who is also making the trip to London. With trips to Baltimore, San Francisco and San Diego, your Houston Texans fall to number eight on the list. Not too bad at all.
Looking at the map above, you can see why this list probably doesn't change much. The "East Coast bias" that some people complain about certainly has some geographical truth to it.
That's about it, readers. I'll leave you with this question: Would you want the Texans to ever participate in a game overseas (like London) if it means losing a true home game? Curious to hear your thoughts. Happy Tuesday.
