1984 Kansas City Chiefs season

Pro Bowl safety Gary Barbaro became the most notable Chiefs player to defect to the rival United States Football League, signing with the New Jersey Generals on February 2 after sitting out the entire 1983 campaign due to a contract dispute.

[1] Barbaro's departure and the trade of cornerback Gary Green began a youth movement that produced the most vaunted secondary in team history.

Cornerbacks Kevin Ross and Albert Lewis, and safeties Deron Cherry and Lloyd Burruss accounted for a combined 13 Pro Bowl appearances for the Chiefs[1] in the years to come.

Maas was named NFL Defensive Rookie of the Year, while Alt eventually became the cornerstone of the club's offensive line later in the decade.

[1] Quarterback Bill Kenney suffered a broken thumb during the preseason and was sidelined until the season's seventh week.

Second-year backup Quarterback Todd Blackledge opened the first six contests of the season and had the club at 3–3.
