Good info, but it's a small sample size and lacks context because teams tend to win more after a bye anyway. From 09 through 14, teams were 82-75-2

Knowing how the NFL works and considering how much they want London games., I wouldn't be surprised if they were purposefully scheduling weak opponents for teams after they play in London. If I get time later, I'll look into the strength of opponents following games in London.
