Wyc Grousbeck may be swapping the parquet floor for the gridiron. The former Boston Celtics control owner is reportedly joining forces with Indian steel magnate Aditya Mittal to launch a bid for the Seattle Seahawks, adding a major international name to what could become one of the most expensive sports franchise sales in history.

The partnership makes sense on multiple levels. Grousbeck and Mittal are already linked through the Celtics' ownership structure, with Mittal investing heavily in the group that purchased the franchise and Grousbeck remaining involved during the transition period. Now, they're taking that connection to the NFL.

The Seahawks aren't just any team hitting the market. They're fresh off a Super Bowl win, which only amplifies their value and appeal. According to Sportico, the franchise was officially put up for sale by the Paul Allen estate after its Super Bowl LX victory, with Jody Allen overseeing the process as executor.

Sportico values the Seahawks at roughly $6.59 billion, but the final sale price could climb much higher—estimates range from $8 billion to $11 billion if multiple billionaire groups push the bidding upward. That's where Mittal's involvement becomes crucial. As CEO of ArcelorMittal and part of one of India's wealthiest business families, he brings the financial firepower needed for a modern NFL purchase.

If their bid succeeds, Mittal would likely serve as the controlling owner, while Grousbeck is expected to be the more visible operating figure around the team. It's a dynamic that blends deep pockets with front-office experience—a combination that could reshape the Seahawks' future.

For now, the sale process is still unfolding, but one thing is clear: the Seahawks are attracting heavyweight interest, and this Celtics-to-Seahawks connection is one to watch.
