Controversy filled the 2015 off-season, as attorney and team spokesperson Mark Fabiani continually bashed the local San Diego city government's efforts to negotiate a replacement for Qualcomm Stadium. When St. Louis Rams owner Stan Kroenke announced in January 2015 his intention to build a new stadium in Inglewood, the Chargers felt pressured to announce their own Los Angeles plan to preserve what they claimed was "25 percent of their fan base" in the affluent Los Angeles and Orange County areas. In February 2015, the team announced a stadium proposal in Carson, in partnership with the Oakland Raiders, their AFC West divisional rivals. In August 2015, San Diego city officials announced their new plan for a new $1.1 billion Chargers stadium at the Mission Valley site of the existing stadium, which included a $350 million contribution of public funds without raising taxes, but Chargers officials scoffed at the proposal and refused to negotiate with the city on any proposal that was not located at the team's preferred downtown location.
