The Miami Dolphins have not won a playoff game in 26 years.But team owner Stephen Ross has turned the Dolphins into a money-making machine.The Miami Dolphins need a new quarterback but don’t have to worry about moneyGettyHow much did Dolphins sell for?With the Seattle Seahawks on the market and potentially fetching a sale price of $11 billion, Ross is cashing in on the overall worth of his AFC East franchise that dates back to 1966.“I don’t think there’s a better asset,” Ross told Bloomberg in January.“I know what I’ve been offered. I mean, numbers you wouldn’t believe.”A man ranked by Forbes as the No. 160 wealthiest person in the world then revealed how much he’s been offered to sell the Dolphins. “Well, I mean, close to $15 billion. Pretty high number,” Ross said. “But you say, ‘Where would you put the money?’ Then what am I going to — what would I do with it?”Everyone can use an extra $125 million, and that is what Ross is set to receive by selling just 1 percent of his team.Lin Bin, who is the co-founder of Chinese electronics company Xiaomi, is worth more than $10bn.Bin will own 1 percent of the Dolphins for $125m, according to multiple reports, by agreeing to a deal with Ross that is pending league approval.Fans stunned at record valuation“What the heck is going on with the prices of these teams? It’s crazy,” one fan tweeted.“Amazing. Crazy how much 1 percent actually is. Nice pay day,” a second fan posted.Stephen Ross could make the biggest team sale in NFL historygettyMike McDaniel’s future was decided after a dismal season with the DolphinsGetty“Are the Dallas Cowboys worth $20bn given this?” a third fan wrote.Miami went a disappointing 7-10 last year, firing Mike McDaniel as head coach amid team chaos and benching starting quarterback Tua Tagovailoa.After being rewarded with a $212m contract, Tagovailoa could now be released by Miami.If that occurs, the six-year veteran will be free to sign with any of the league’s other 31 teams.Either way, Tagovailoa will hope to rebound from an uneven 2025 campaign that saw him complete 67.7 percent of his passes but only throw 20 touchdowns while recording 15 interceptions and going 6-8 as a starter.Owner wins even when Dolphins lose Ross is flush with cash no matter what happens to Tagovailoa.Tyreek Hill will be a free agent for the first time in his NFL careerThe 85-year-old is still the majority owner of the Dolphins and has no plans to sell the team.But Ross, a former real estate magnate and tax attorney, isn’t completely unwilling to move on from his sports properties.He sold a 13 percent stake in the Dolphins, the Formula One Miami Grand Prix and the Miami Open in December 2024 for $8.1bn.The Washington Commanders sold in 2023 for a NFL record $6.05 bn.The Los Angeles Lakers topped that eye-watering mark last June with a $10bn value that became the largest sale of a professional sports franchise in the world.If Ross ever moves on from the Dolphins, he could receive a record $12.5bn in return — and that number should only increase year after year.Stay up to date with the latest from the NFL across all platforms – follow our dedicated talkSPORT USA Facebook page and subscribe to our talkSPORT USA YouTube channel for all the news, exclusives, interviews and more.
