Carolina Panthers: David Tepper
When Tepper bought the Panthers for $2.3 billion in 2018, it wasn't just the most anyone had ever paid for an NFL team -- it was among the highest price tags in the history of North American sports. It was still a drop in the bucket for the renowned hedge fund manager, who was previously a minority owner of the Pittsburgh Steelers.
Chicago Bears: Virginia Halas McCaskey
Halas McCaskey, 101, is the longest-tenured owner in the NFL and the oldest owner in major U.S. professional sports. One of 10 current female owners in the league, she inherited the team from her father, George Halas -- the legendary Bears founder who won 324 games and six NFL titles as a coach and owned the team from 1921 until his death in 1983.
Cincinnati Bengals: Mike Brown
Brown has owned and operated the Bengals since the 1991 death of his father, Paul Brown, who co-founded and coached both the Bengals and the rival Cleveland Browns -- a franchise named after him.
Cleveland Browns: Dee and Jimmy Haslam
Jimmy Haslam, whose father founded the nation's largest truck stop chain (Pilot Flying J), became CEO of the company in 1996 and bought a minority stake in the Pittsburgh Steelers in 2008. He sold it four years later to buy the Cleveland Browns for a reported $1.1 billion in 2012. He and his wife, Dee, also own the Columbus Crew (MLS) and a stake in the Milwaukee Bucks (NBA).
