When/If the new stadium gets built here in Inglewood, the Chargers and Rams will also share a stadium.
RWA - part of the problem too is, even if they did set up the conferences to have teams near each other, at some point one of them will demand the taxpayers pay for a new stadium and nobody will and they'll move to another city and screw the whole thing up, so it's best not to plan anything around where the team is located.
