Is Graham Walker related to Patrick Mahomes? Meet Rice tight end hoping to follow half-brother's NFL footsteps

The NFL family is set to grow by over 300 members as the 2025 NFL Draft process will include 257 draftees and dozens of undrafted free agents.

Among the new additions to the NFL family is a group of players who share real family ties with NFL players. Rice tight end Graham Walker is one of those draft hopefuls.

Walker, who caught 24 passes for 252 yards with the Owls in 2024, is more of an under-the-radar draft prospect. That said, fans are probably pretty familiar with his NFL family tree.

“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 of Walker.

Walker and his half-brother have met a few times, but do not share a particularly strong brotherly bond. With Walker potentially joining Mahomes in the NFL, however, their bond could grow rapidly.
