Best: Kansas City Chiefs – Len Dawson
After Len Dawson set the record for most touchdown passes thrown in a single season by the quarterback of the Kansas City Chiefs (30) way back in 1964, that record stood for 54 years, until Patrick Mahomes broke it in late 2018. Since Mahomes has quite a ways to go to be mentioned in this vein, Dawson gets the nod for the best quarterback in the history of the Chiefs’ franchise, as the only quarterback that has ever taken the Chiefs to the Super Bowl, and the MVP of Super Bowl IV, which is the franchise’s only win in the big game.
Dawson also has more than twice as many touchdown passes in franchise history (237) than the guy behind him, Trent Green (118).
Worst: Kansas City Chiefs – Todd Blackledge
The Kansas City Chiefs thought so highly of Todd Blackledge that they made him the seventh pick of the 1983 NFL Draft, ahead of future Hall of Fame quarterbacks like Jim Kelly and Dan Marino. Even Blackledge himself admitted to being surprised that the Chiefs selected him over some of the other quarterbacks in the draft, and expected to hear his name called somewhere closer to the second round of the draft.
He spent most of his career being pulled in and out of games by the Chiefs coaching staff, never throwing for more than 1,707 yards in a season. After seven forgettable seasons in the NFL, Blackledge retired.
