Pitting Giants owner John Mara's net worth vs. Dolphins owner Stephen M. Ross: Which billionaire comes out on top?

John Mara's New York Giants and Stephen M. Ross' Miami Dolphins are facing off in Week 5 of the 2022 NFL season. Both teams head into the game with vastly different records.

The New York Giants owner John Mara has an estimated net worth of $500 million, according to Celebrity Net Worth. Mara is the latest person in his family to own the Giants, as both his father and grandfather once occupied the roles. John Mara would love nothing more than a resounding win against the Dolphins to get his team on the right track.

On the other hand, the Miami Dolphins' owner Stephen M. Ross has a net worth of $9 billion, according to CA Knowledge. The flamboyant real estate developer has invested a lot in the Miami Dolphins over the years. He too would like a win in Week 5 to show that the Dolphins' electric start to the year wasn't a fluke.

The Miami Dolphins have started the season 3-1 and were on a three-game winning streak before their Week 4 defeat to the Buffalo Bills.

On the other hand, the New York Giants head into the game with a dismal 1-3 record. Daniel Jones and Co. have lost their last two games without putting much of a fight. They'll need to get a result against the Dolphins to keep their slim playoff hopes alive.

Both the Giants and Dolphins will have their super-rich owners watching from a vantage point.

Where do John Mara and Stephen M. Ross rank among the NFL's richest owners?
