The Kansas City Chiefs held their rookie minicamp last weekend. It featured 87 players, 60 of whom were reportedly invited on a tryout basis.

One of the many invitees was quarterback Patrick Mahomes' half-brother, Graham Walker. The former Rice tight end, who is listed at 6'3" and 227 pounds, is a converted wide receiver who transferred from Brown University.

"He's supportive, as he always is. Hopefully, in this offseason, Patrick will get a chance to throw the ball to him," said Mahomes Sr. during an interview with FOX 4 Kansas City last year, "run routes, as Patrick always has his receivers come down."

He finished his last college season with 44 receptions for 515 yards and six touchdowns. He previously played three seasons at Brown, his best season being his first year, when he caught 53 passes for 658 yards and six touchdowns.
