The world of sports branding is facing a sudden deep freeze (pun intended). The original ‘Iceman’ George Gervin, has filed to protect his legendary moniker after one NFL star tried to stake a claim on it. Caleb Williams, the Chicago Bears quarterback, attempted to trademark the ‘Iceman’ nickname for himself.. Within days, the NBA legend and his team responded with a stern reminder of who built the Iceman brand.

On March 16, Caleb Williams filed for four trademark applications on the Iceman name, a logo, and two silhouettes of his iconic jump pass to Rome Odunze. Reports claim he intends to build a Jumpman-like brand around it. But he may not have done his homework.

Within four days of Williams’ filings, George Gervin filed his own applications to protect the nickname. Gervin, who played in the NBA from 1972 to 1986, mostly with the Spurs, was bestowed the nickname by a teammate in 1973. For five decades, he’s been the only Iceman the sports world has known.

“I’ve got nothing but respect for [Williams],” Gervin told the Chicago Sun Times. “He’s already proved greatness, and his potential upside is great. Like an ‘Iceman.’ But that name is taken. . . . All I’m saying is: Young fella, we’ve already got one ‘Iceman.’”

The 73-year-old has applied for trademarks for ‘Iceman’ and ‘Iceman 44,’ an ode to his jersey number. It’s a direct challenge to Williams’ brand ambitions, and Gervin isn’t standing alone.

Spurs stand on business for George Gervin

The San Antonio Spurs, where George Gervin spent the majority of his legendary career, were quick to rally behind their icon. They tweeted a picture of the Iceman himself on his icy throne, which gave off vibes of the Ice King from Game of Thrones. The message was short and unambiguous.

“There’s only one Iceman 🥶,” declared the Spurs.

Williams earned his nickname just a year ago through a clutch performance in the 2025–26 Wild Card win over the Green Bay Packers. Most fans don’t even know he had the Iceman nickname. The Spurs are clearly pointing out that Gervin has held that moniker for far longer.

The nickname is so synonymous with Gervin that his own business partner assumed it was already protected. Jerald Barisano, president of Gervin Global Management, said he mistakenly believed the trademark was already officially registered. They’re now relying on the US Patent and Trademark Office to recognize decades of established use.

If the USPTO sides with the original Iceman, Williams will have to find a different hook for his personal brand and build it from scratch.
