6 Major league teams in one city I think only NY can support.
If I could decide this issue looking only what change could be made to improve the product on the field I would move the Chargers to LA, really, those games in San Diego have been awful in recent years, I don't remember the last great Chargers game in their own stadium and it looks like they play 16 games on the road, that reflects on the field, too many poor games there, ok that they had many problems in roster management, injuries etc but a SNF or MNF in San Diego is almost a guaranteed ugly game.
