For many football fans, Roger Goodell is the only NFL Commissioner they’ve known, with the 65-year-old now in his 19th year at the helm of America’s most popular pro sport. In an episode of “The David Rubenstein Show: Peer to Peer Conversations,” Goodell talks about NFL’s international expansion, and that adding an 18th game to the regular season schedule is the “logical” next step for the league. He also discussed the NFL allowing private equity firms to take passive minority stakes in teams. There’s been some fan backlash on this move, but Goodell tried to ease those concerns, saying he doesn’t think he’ll “ever allow institutional [investors] in a controlling position, at least in the foreseeable future.” This interview was recorded January 3 in New York.
