On Saturday, NFL commissioner Roger Goodell said no team will move to Los Angeles next season. The Raiders, San Diego Chargers and St. Louis Rams were all considered potential teams to move, and the Raiders were also linked to San Antonio.
According to ESPN's Adam Schefter, Goodell told those three teams that anyone considering moving to L.A. should target 2016.
