The Thunder's Secret Weapon: How Superfan Thundor Masters Free Throw Defense
Garrett Haviland, better known as Thundor, has become a legendary figure in Oklahoma City for his unique approach to supporting the OKC Thunder. His antics, particularly during free throws, have earned him the title of the team's unofficial free throw defense specialist.
The Birth of Thundor
Haviland's journey began during the Thunder's inaugural season in 2008-09. Inspired by a fan competition, he crafted a costume inspired by Jack Black's Nacho Libre and armed himself with a megaphone. His first attempt to distract Chris Kaman of the LA Clippers didn't yield immediate results, but it sparked an idea that would evolve into a game-day ritual.
The Evolution of Free Throw Defense
Over the years, Haviland has perfected his craft. He now dons elaborate chest paintings, uses a megaphone to amplify his signature "WHOOP," and employs a variety of antics to rattle opposing players. His efforts have disrupted the likes of Kenyon Martin, Dwight Howard, and Paolo Banchero, making him a formidable presence at the free-throw line.
The Impact on the Game
While not every attempt is successful, Haviland's presence has undeniably influenced the game. His distractions have led to missed free throws at critical moments, often shifting the momentum in favor of the Thunder. Despite the rise in opponent free-throw percentages at Paycom Center, Haviland remains committed to his role, always seeking new ways to enhance his impact.
The Man Behind the Mask
By day, Haviland works at a behavioral health company, helping individuals with developmental disabilities. His job requires extensive travel across the state, but he always makes time to transform into Thundor for Thunder home games. His dedication to both his profession and his fandom showcases his passion and commitment.
A Legacy of Laughter and Support
Haviland's Thundor persona has become a beloved part of the Thunder community. His ability to make others laugh while supporting his team has earned him widespread admiration. As he continues to evolve his free-throw defense tactics, one thing remains clear: Thundor is more than just a superfan—he's a vital part of the Thunder's identity.
