Graham Walker played this past weekend at the Chiefs rookie minicamp to try and earn a longer-lasting NFL contract. But the half-brother of Patrick Mahomes appears to have missed out on any kind of deal.

When you're trying to make an NFL team as a tight end or a wide receiver, it helps to have some chemistry with the starting quarterback, which is why Graham Walker might have a leg up on the competition during Kansas City's rookie minicamp this week.

Graham Walker, who is the half-brother of quarterback Patrick Mahomes, will be a part of the camp, according to ArrowheadPride.com. He is also the son of Patrick Mahomes Sr, but he grew up in Vermont with his mom, Jessamyn Walker, and stepfather, Gerry Howatt.
