“Patrick Mahomes’ Half-Brother Is Trying Out for the NFL—And You Won’t Believe Where He Played

It’s not every day a potential NFL player turns heads because of where he came from—and who he’s related to. But Graham Walker is no ordinary rookie. The tight end, now making waves at an NFL rookie minicamp, is the half-brother of none other than Patrick Mahomes, the two-time Super Bowl MVP and face of the Kansas City Chiefs. And the most surprising part? Walker didn’t play at Alabama, Georgia, or Ohio State—he played at Brown University and later at Rice.

Walker’s football journey didn’t follow the traditional path to the pros. While most NFL hopefuls come from powerhouse programs, Walker chose the Ivy League for both academics and athletics. At Brown, he built a reputation as a reliable, smart, and physical tight end who could contribute in both the passing game and run blocking. He later transferred to Rice University, where he faced tougher competition and continued to grow as a complete player.

Standing 6-foot-3 and weighing in at 235 pounds, Walker has the ideal frame for the position. But what truly sets him apart is his mental toughness and drive—qualities that have kept him grinding through years of being overlooked. He may not have drawn national media attention during college, but that changed the moment his family connection was revealed.

Graham is the son of former MLB pitcher Pat Mahomes, making him Patrick Mahomes’ half-brother. While they were raised separately and pursued different paths, their athleticism and competitive spirit clearly run in the family. Patrick’s NFL stardom has cast a massive shadow, but rather than bask in the glow, Graham has stayed grounded—quietly working toward his own dream.

Now, he’s been invited to participate in an NFL rookie minicamp, a critical first step for undrafted players to prove themselves. It’s a grueling process: days of practice, evaluation, and little room for error. For most, it’s a long shot. But Walker has been defying odds his whole life, and this camp is no different.

Coaches and scouts have already taken notice of his discipline, football IQ, and team-first mentality. Those who know him say he’s not using the Mahomes name for advantage—he’s using it as motivation. He’s determined to build his own legacy, one rep at a time.

Because in a league obsessed with pedigree, Graham Walker is proof that sometimes greatness comes from the most unexpected places.
