The National Football League wants to put at least one franchise in Los Angeles by the start of next season. Kroenke, the owner of the St. Louis Rams and arguably the most powerful owner in sports, wants it to be his. He’s ready to build a $1.9 billion stadium southwest of downtown. He has big backers. Jones, who built an 80,000-seat cathedral to excess known as “Jerry’s World” for his Cowboys in 2009, admires the grandeur of Kroenke’s plan and has sided with him against owners from the San Diego Chargers and Oakland Raiders, who want to build and share a stadium in the L.A. suburb of Carson, bringing two franchises to the city at once. ... Kroenke aims to turn a demolished horse racing track and parking lot in Inglewood, Calif., into an 80,000-seat stadium with a latticed open-air roof; an adjacent 6,000-seat arena; 1.7 million square feet of retail and office space; 2,500 residential units; and a hotel. To put the Rams there, he’ll have to secure the approval of at least 24 of 31 of his fellow NFL owners and give a stiff arm to his native Missouri. ... Along with the Rams, Kroenke owns the National Basketball Association’s Denver Nuggets, the National Hockey League’s Colorado Avalanche, Major League Soccer’s Colorado Rapids, and two-thirds of the English Premier League soccer club Arsenal—all separate from his wife Ann’s $3.8 billion inheritance.
