I know the Bills are traveling Thursday which is what most teams do and they will try to adjust to the time difference. When I travel for work, I try and stay on East coast time which is what many teams do when they travel coast to coast within the states, I am curious why they dont try to do that for ondon. THe game is at 9:30Am EST which is not an unreasonable time to play a game for someone who lives on the east coast, sure you have to get up a little early that day....it is not uncommon to have practice that early during TC......
Here is what I would consider. Travel Saturday early...say leave at 8AM-ish EST and arrive in London at around 2-3PM EST....get to the hotel, get a walkthrough in , go to bed close to your normal EST which will be very early for London, close the blinds in the hotel and just pretend you are at home. Wake up, do the game, get to the airport and go home....no special play in London (do that on your own time in the offseason).....just treat it like any other away game.
