Three-time Super Bowl winner Patrick Mahomes was among nine people enshrined in the Texas High School Football Hall of Fame on Saturday — and he left a piece of himself in his home state.

Mahomes played at Whitehouse High School, near Tyler, Texas, and went on to Texas Tech before the Kansas City Chiefs selected him in the first round of the 2017 NFL Draft.

Mahomes announced on Instagram after the ceremony that he and his sponsor, Adidas, will be partnering with 15 high schools, including his alma mater.

“Whitehouse, Texas is where it all began,” Mahomes said. “It’s an honor to be inducted into the Texas High School Football Hall of Fame.”

He continued:

“As a part of this recognition, I’m proud to announce that @adidasfballus and I are signing 15 high schools to Team Mahomes that will represent my Gladiator logo on uniform, starting with Whitehouse High School. This is just the beginning.”

Mahomes played football, basketball and baseball at Whitehouse, graduating in 2014. As a senior, he passed for 4,619 yards and 50 touchdowns, and he also ran for 948 yards and 15 scores.

Last summer, Texas Tech signed on to the Gladiator team, becoming the first program to have the logo featured on official collegiate apparel.

Other benefits available to the high school team under the partnership were not announced.

Also enshrined Saturday was Robert Griffin III, the 2011 Heisman Trophy winner. He played at Copperas Cove High School, near Waco, Texas, before enrolling at Baylor in 2008.
