At just 28, Patrick Mahomes is a two-time NFL MVP and Super Bowl champ. His secret? A pair of red underwear he’s worn to every NFL game in his six-year career. Former Chiefs quarterback Chad Henne revealed this during an interview with ESPN’s Adam Schefter, who was surprised by the quirky ritual. Mahomes confirmed it in a Monday Night Football interview, explaining his wife Brittany gave them to him, and he’s worn them since his successful first season.

Mahomes only wears the underwear on game days and washes them occasionally, but not during a winning streak. His superstitions extend to a strict pre-game routine, which he showcased on Netflix’s “Quarterback.”

Mahomes has been with the Chiefs since 2017 and signed a 10-year, $450 million extension in 2020. He’s set to earn $210.6 million between 2023 and 2026, potentially reaching $218.1 million by 2026.
