He then joined the Kansas City Chiefs and anchored an AFL championship team in 1966 and a world championship team in 1969.

Buck Buchanan was the Chiefs "big man" on defense, standing 6-foot-7 and weighing in at 287 pounds. He was twice voted by his teammates as the team's MVP and earned six AFL All-Star berths and two in the NFL. He played in 166 consecutive games from 1963-74 and redefined the way defensive linemen played their positions.

Because of is size and speed, he was often double-and-triple teamed by an opponent. That would free up his teammates to make sacks and tackles while Big Buck manhandled half the offensive line. He batted down 16 passes in 1967 and recorded the first sack in Super Bowl history when he decked Green Bays Bart Starr.

"I remember the things the NFL players were saying about the AFL, and it hurt Ð things like calling us Mickey Mouse," Buchanan said. "I was proud to be in that first Super Bowl. But the real pride came when we won Super Bowl IV. It was so different. We went into that game knowing we would win."

On Aug. 4th, 1990, Buck Buchanan became the fifth Chiefs player to be enshrined in the Pro Football Hall of Fame. With his inception into the Hall of Fame, he became the first AFL defensive lineman to be immortalized in the hallowed halls of Canton, Ohio's Pro Football Hall of Fame.
