NOTES: This list doesn't include the Titans, which is owned by KS Bud Adams Enterprises, which is divided in thirds between the late Bud Adams' two daughters and the family of his deceased son. It also doesn't include the Packers, who are publicly owned. Buccaneers owner Malcolm Glazer passed away on May 28, and the plans are to keep the team in the family with his wife Linda and their five sons and one daughter. The 49ers are also not reflected in this snapshot, as there are multiple layers of ownership.
