NFL owners voted Tuesday night to allow the Saint Louis Rams to move to a new stadium just outside Los Angeles, and the San Diego Chargers will have an option to share the facility, The Associated Press has learned.  The Oakland Raiders, who also wanted to move to the area, were left out of the deal, according to a source familiar with the negotiations.  The source requested anonymity because he wasn’t cleared to talk about the vote, which ended the NFL’s 21-year absence from the nation’s second-largest media market.  The compromise was that the Chargers and Raiders wanted to share a new stadium in Carson, California, and the Rams wanted to move to nearby Inglewood, and this was approved by a vote of 30 to 2 after the other options did not get the 24 votes needed for approval.  The Chargers can continue to negotiate with San Diego for a new stadium deal, while keeping the option of joining the Rams and owner Stan Kroenke at the $1.8 billion complex he is building.  The Rams were based in the Los Angeles area from 1946 to 1994 and will play in a temporary facility, which will probably the Los Angeles Coliseum, until the new stadium is ready, most likely for the 2019 season.
