Rice tight end Graham Walker has declared for the NFL Draft and could soon join the growing list of siblings playing in the league. Walker is the half-brother of Kansas City Chiefs quarterback Patrick Mahomes.
After recording 24 receptions for 252 yards and zero touchdowns in his lone season at Rice, Walker’s statistical output likely won’t be enough to earn him a selection in the draft. His best shot at making it to the NFL will be as an undrafted free agent.
The 2025 NFL Draft continues with Rounds 2 and 3 on Friday, April 25 and Rounds 4 through 7 on Saturday, April 26.
Is Graham Walker Related to Patrick Mahomes?
Yes, Graham Walker is Patrick Mahomes’ half-brother. They share the same father, former MLB pitcher Pat Mahomes Sr.
Patrick Mahomes is the eldest son of Pat Mahomes Sr. and his ex-wife Randi Martin. The elder Mahomes also shares a son, Jackson Mahomes—a social media personality—with Martin.
Graham Walker, on the other hand, is the son of Pat Mahomes Sr. and Jessamyn Walker. The two were never married.
The Mahomes Family: Other Siblings
Pat Mahomes Sr. had a successful MLB career, pitching for six teams between 1992 and 2003, along with a one-year stint in Japan with the Yokohama BayStars of Nippon Pro Baseball. After his divorce from Martin, he had another son, Tyler Mahomes, with Karen Kramer, and later had Graham with Jessamyn Walker.
He also has three younger daughters: Zoe, Mia, and Avery.
Although Graham is part of the Mahomes family, he was raised in Vermont by his mother, Jessamyn, and stepfather, Gerry Howatt, and therefore carries his mother’s surname. He also has two half-sisters on his mother’s side.
Graham reconnected with his biological father in adulthood, and Pat Mahomes Sr. played a role in helping him choose Rice University to continue his football career.
While Graham has met Patrick Mahomes multiple times, the two do not share a close relationship. Patrick has reached out occasionally to offer words of encouragement.
Walker is currently in Vermont with his family as the NFL Draft unfolds. He began his college football career at Brown University, where he was a standout in the Ivy League. Over three seasons at the Division I FCS level, he amassed 127 receptions for 1,496 yards and 15 touchdowns, earning All-Ivy honors in both 2022 and 2023.
Despite a down year at Rice, Walker hopes his strong college tape and prior production will be enough to earn him a shot with an NFL team. The signing period for rookie free agents begins immediately after Round 7 concludes in what is sure to be a feeding frenzy of sorts.
