Dawson led the Texans/Chiefs to three American Football League Championships (1962, 1966, 1969), and a victory in Super Bowl IV, for which he won the game's MVP award. Dawson retired from professional football after the 1975 season, and was inducted into the Pro Football Hall of Fame in 1987. He is sports director at KMBC-TV in Kansas City and color analyst for the Chiefs Radio Network.
Dawson was the ninth of 11 children of Ohio native James and England-born Annie Dawson. He attended Alliance High School in Alliance, Ohio. He was MVP of the football team and was named outstanding Ohio back of the year by the International News Service. A three-sport athlete, Dawson set school records in football and in basketball, and was the first athlete in 13 years to be named first-team all-state in both sports during the same year.
During the recruiting process, Dawson had to choose between Ohio State University in Columbus and Purdue University in Indiana. While he was reluctant to take over Woody Hayes' split-T offense with the Buckeyes, the true reason for his selection of Purdue stemmed from the chemistry he had established with a Boilermaker assistant coach, Hank Stram, beginning a friendship that would last for more than a half century. During three seasons with the Boilermakers, Dawson threw for over 3,000 yards, leading the Big Ten Conference in that category during each campaign. While at Purdue, Dawson was initiated into the Alpha Tau Omega fraternity.
As a sophomore in 1954, Dawson put together an outstanding first season as the NCAA's leader in pass efficiency, while also playing defense and serving as the Boilermaker kicker. Blessed with a strong offensive line, he threw four touchdown passes in a 31-0 victory over the University of Missouri, then later engineered a huge upset of the University of Notre Dame, which had entered the contest on a 13-game winning streak.
Despite his status as a first round pick in the 1957 NFL draft, Dawson was unable to make an impact with the Pittsburgh Steelers. Following his rookie campaign, his status in the Steel City became even more tenuous when the Steelers acquired future Hall of Famer Bobby Layne early in the 1958 season. Failing to dislodge the colorful signal caller, Dawson was then traded after the 1959 season to the Cleveland Browns on December 31.
After encountering similar problems in battling Browns' quarterback Milt Plum, Dawson was released, having completed only 21 passes for 204 yards and two touchdowns in his five seasons of NFL play. However, he soon found his calling when he signed with the American Football League's Dallas Texans on June 30, 1962. The move reunited him with Stram, who was beginning his third year as the Texans' head coach.
In that first season, 1962, Dawson led the league in touchdowns and yards per attempt, and was The Sporting News' selection as the AFL MVP. He also led Dallas to the first of three league titles in a thrilling double-overtime victory over the two-time defending champion Oilers in Houston. Dawson ran a ball-control offense in the 20-17 win, and tossed a 28-yard touchdown pass to halfback Abner Haynes. The team then moved north to Kansas City and were renamed The Chiefs in 1963. Dawson was also selected by his peers as a Sporting News 1966 AFL All-League player.
A pinpoint passer, Dawson's mobility helped him flourish in Stram's "moving pocket" offense. He would win four AFL passing titles and was selected as a league All-Star six times, ending the 10-year run of the league as its highest-rated career passer. From 1962 to 1969, Dawson threw more touchdown passes (182) than any other professional football quarterback during that time. In 1966, Dawson led the Chiefs to a, 11-2-1 record and a 31-7 win over the Buffalo Bills in the AFL championship game, earning his team the honor of representing the AFL in Super Bowl I, the first championship game between the AFL and their NFL rivals. The NFL champion Green Bay Packers won easily, 35-10, but Dawson had a fairly good performance in the game, completing 16 of 27 passes for 210 yards and a touchdown, with 1 interception.
While he threw for more than 2,000 yards in each of the previous seven campaigns, Dawson's 1969 season with Kansas City would be his most memorable by making a dramatic comeback from a knee injury suffered in the season's second game. The injury was first feared as season-ending, but after missing five games, Dawson went on to lead the Chiefs to road playoff victories over both the defending champion New York Jets and the Oakland Raiders.
He then capped his year with MVP accolades in Super Bowl IV, the last game ever played by an American Football League team. In the game, Dawson paced the Chiefs to a win over the NFL's heavily favored Minnesota Vikings by completing 12 of 17 passes for 142 yards and a touchdown, with 1 interception, and rushing for 11 yards. The performance was especially notable given the fact that he had been linked to a gambling investigation (by an unrelated gentleman who was named Donald Dawson) in the days leading up to the game.
With the league's absorption into the National Football League in 1970, Dawson earned one final honor from the league as a member of the second team All-time All-AFL Team. He is also a member of the Chiefs' Hall of Fame and the Pro Football Hall of Fame. He would earn Pro Bowl honors following the 1971 NFL season, then ended his career in 1975, having completed 2,136 of 3,741 passes for 28,711 yards and 239 touchdowns, with 181 interceptions. He also gained 1,293 rushing yards and 9 touchdowns on the ground. On November 1, 1970, the Chiefs led the Oakland Raiders 17-14 late in the fourth quarter. Facing third and long, a run by Dawson apparently sealed victory for the Chiefs, but as Dawson lay on the ground, he was speared by Raiders’ defensive end Ben Davidson, who dove into Dawson with his helmet, provoking Chiefs’ receiver Otis Taylor to attack Davidson. After a bench-clearing brawl, offsetting penalties were called, nullifying the first down under the rules in effect at that time. The Chiefs were obliged to punt, and the Raiders tied the game on a George Blanda field goal with eight seconds to play. Taylor’s retaliation against Davidson not only cost the Chiefs a win, but Oakland won the AFC West with a season record of 8-4-2, while Kansas City finished 7-5-2 and out of the playoffs.
Dawson announced his retirement as a player in May 1976, shortly before turning 41.
In 1966, while still playing for the Chiefs, Dawson became sports director at KMBC-TV in Kansas City. On March 16, 2009, Dawson announced he would step down from anchoring on a nightly basis. He will still report for KMBC during the Chiefs football season and will fill in when other anchors are on leave. Since 1985, Dawson has also been color analyst for the Chiefs radio broadcast team.
From 1977 to 2001, he served as the host of HBO's Inside the NFL, and also worked as an analyst for NBC's AFC coverage from 1977-1982.
In 1985, Dawson began serving as a color commentator for the Chiefs Radio Network. He currently works with Mitch Holthus and former Chiefs player Kendall Gammon.
In 1987, Dawson was recognized for his play with the Chiefs with his induction into the Pro Football Hall of Fame.
In 1996 Dawson was honored by his alma mater and inducted into Purdue's Intercollegiate Athletics Hall of Fame.
In 2006, Dawson was interviewed for the NFL Network documentary America's Game: The Super Bowl Champions chronicling the 1969 Kansas City Chiefs season.
In 2008, Dawson teamed with Depend to encourage men to visit their doctors and be screened for prostate cancer. In 2008, Dawson was awarded the Walter Camp Distinguished American Award.
In 2010, Dawson presented the New Orleans Saints and another Purdue quarterback, Drew Brees, with the Vince Lombardi Trophy after their victory in Super Bowl XLIV.
In 2012, Dawson was honored with the Pete Rozelle Radio-Television Award for his longtime contributions as a sports broadcaster.
Today, Len works at KMBC, a Kansas City news station, as a sports anchor.
Dawson was married to his high school sweetheart, Jackie, in 1954; they were married 24 years, until her death in 1978 at age 42 (she had suffered a stroke the previous year). They have two grown children, Lisa Anne and Len Jr. Dawson is married to his second wife, Linda, and they live in Kansas City.
Dawson is a seventh son of a seventh son. In 1991, Dawson was diagnosed with prostate cancer.
