Auto parts entrepreneur Shad Khan added another sports team to his holdings, snapping up middling Premier League soccer club Fulham for $300 million in July 2013, a year and a half after purchasing the NFL's Jacksonville Jaguars for $770 million. The Jaguars endured a rough 2-14 season, and Khan canned his coach and general manager after the season. Meanwhile, his auto parts manufacturer Flex-N-Gate rolls along, with $3.9 billion in 2012 sales.
