While Kansas City Chiefs star QB Patrick Mahomes is known for his electrifying skills on the field, he’s also known for his supportive family, including his four siblings. Jackson, Zoe, and Mia are more used to the spotlight; however, Patrick has another half-brother who likes to work hard but prefers to stay in the shadows.
We’ll share everything we know about his half-brother, Graham Walker.

Meet Graham Walker, Patrick Mahomes’ Half-Brother and Rice University Playmaker
Mahomes’ most infamous sibling is his younger brother, Jackson Mahomes. However, he has three half-siblings — two half-sisters and his half-brother, Graham Walker.
Walker is the third son of Mahomes’ father, Pat Mahomes Sr.
“They say he’s the one who looks most like me, but maybe the other boys will disagree a little bit, but he’s definitely a Mahomes,” Mahomes Sr. said in an interview with Fox 4 in Kansas City.
Although Mahomes Sr. is his biological father, Walker was raised by Jessamyn Walker and Gerry Howatt. Additionally, he has two other siblings, his sisters Mireille and Kayla. Walker and Mahomes Sr. haven’t had a normal relationship but have kept in contact.
“His manners are intact, his stepdad did a great job with him, his mom did a great job with him, and now I’m getting the chance to put my hands on him a little more,” Mahomes Sr. said.
“[Graham] finally decided he wants to be a serious football player, so we have him in the transfer portal,” Mahomes Sr. went on. “Hopefully he’s going to choose a school here soon and we can go on with the next chapter.”
He eventually chose to transfer to Rice University. With impressive stats from his previous three seasons at Brown — 127 catches, 1,496 yards, and 15 touchdowns — all eyes were on Walker after he changed schools. However, this season, the tight end caught just 24 passes for 252 yards and zero touchdowns.
Standing at 6’3″ and weighing 215 pounds, Walker’s physical presence is similar to that of his famous brother, but he hasn’t been able to duplicate Patrick’s success.
“He’s come to the realization that he has a chance to play in the NFL, so he’s going to try and go out and explore all the possibilities,” his dad said last year. “[He’ll take] whatever road that leads to try to give himself a chance to play at the next level like we all want to.”
Although they didn’t grow up together, Walker and Mahomes have met multiple times.
“[Patrick] is supportive,” Mahomes Sr. said. “He’s supportive as he always is. Hopefully, in this offseason, Patrick will get a chance to throw the football to him as he runs routes as Patrick always has his receivers come down, so we’re looking forward to that.”
The family hopes Mahomes can help open up an opportunity for Walker.
“You know, his word may be a little good, so maybe he can get [Graham] in the door too,” Mahomes Sr. said.
Chiefs vs. Eagles Super Bowl Preview
Based on PFN’s win probability model, which ran 10,000 simulations via the PFN Playoff Predictor, the Eagles have a 52.8% chance of defeating the Chiefs.
The Chiefs are aiming to become the first team in NFL history to win three straight Super Bowls. Kansas City has won three of the last five Super Bowls and will be the first NFL team to play in five Super Bowls over a six-season span.
This is Philadelphia’s third Super Bowl appearance in the last eight seasons. The Eagles defeated the New England Patriots in Super Bowl LII and lost to the Chiefs two seasons ago in Super Bowl LVII.
Kansas City Chiefs Trends and Insights
- The Chiefs have 17 straight one-score wins (12-0 this season, their last three playoff games last year, and their last two regular season games). Twelve one-score wins is the most in a single season all-time, tied with the 2022 Vikings, 2019 Seahawks, and 2015 Broncos.
- Patrick Mahomes passed Joe Montana for the second-most playoff wins by a starting quarterback (17) and John Elway for the second-most playoff game-winning drives by a quarterback (seven).
- From 2019-24, the Chiefs have made six Super Bowl appearances, are chasing a fourth title, and have won 78% of their regular season games. For reference, the Splash Brother Golden State Warriors (2015-19, 2022) made six NBA Finals appearances with four titles and won 76.2% of their regular season games.
- The Chiefs have averaged over 2.5 points per offensive drive in four straight games when playing their regulars – that’s a good formula, as NFL teams have won 78.9% of their games this season when clearing 2.50 PPD.
- During his career, Mahomes has averaged 3.9 carries for 20 yards and 0.13 touchdowns on the ground during the regular season. In the postseason, those rates elevated to 5.4 attempts, 29.1 yards, and 0.35 touchdowns per game.
Philadelphia Eagles Trends and Insights
- The Eagles peaked early last season and scored 155 points over a five-game win streak (Weeks 7-12). Over their past five games, they’ve scored 166 points.
- Jalen Hurts ran for three scores in his prior Super Bowl experience, joining Terrell Davis as the only player to do that in The Big Game. With his three rushing scores on Sunday, Hurts joined LeGarrette Blount as the only players in NFL history with multiple playoff games in which they ran for three-plus touchdowns.
- Philadelphia has forced 19 turnovers in their past six games, a run that includes four games with three-plus.
- The Eagles became the sixth team to have multiple players rush for multiple scores in a playoff game, the first since Rex Burkhead and Sony Michel did it for the 2018 Patriots.
- Since 2022, the Eagles are 18-8 ATS (69.2%) when facing a team that enters play with at least as many wins as losses (second best, trailing only the 20-6-1 Lions).
- Hurts will become the eighth quarterback to start multiple Super Bowls within his first eight seasons. Of the previous seven, only Elway failed to secure a ring within his first five seasons—though Elway would famously cap off his career with Super Bowl victories in his final two seasons.
