Rumor about relocation and possibly being put in the AFC East. Never should have left SD but its obvious LA isn't working. https://www.cbssports.com/nfl/news/...ct-patriots-others-with-huge-afc-realignment/
Talk about home field advantage if this were to happen. And equally tough road games for them. The home/away splits would probably be absurd.
Logistically they would gain an advantage but not in terms of support. I don't think I've ever come across a Chargers fan in the UK and very few UK fans will switch allegiance. It would be playing every game in a neutral stadium, at best, and for some match ups more like a road game.
