Biography

Corey Matthaei enters his fifth season with the Chiefs and his third as the team’s assistant quarterbacks coach in 2017. In addition to tutoring the quarterbacks, Matthaei will also assist offensive line coach Andy Heck, working with the offensive line. Before being promoted in 2015, Matthaei was an offensive quality control coach for two seasons with the team and spent five seasons with the Philadelphia Eagles as a coaching assistant.

Since Matthaei's arrival in Kansas City in 2013, he has assisted QB Alex Smith in owning a 64.5 completion percentage, which ranks first among all Chiefs quarterbacks with at least 700 passing attempts. Under Matthaei's guidance, Smith has also recorded four consecutive seasons passing for 3,000 yards since joing the franchise in 2013. Smith became the franchise’s all-time leading rusher among QBs after the 2016 season (1,317 yards).

Running Back Jamaal Charles led the NFL in first downs (104), ranked second in yards from scrimmage with 1,980 and recorded the most receiving (693) yards by a running back in Chiefs history. QB Alex Smith threw only seven interceptions, ranking him first in the NFL for fewest interceptions (min. 300 attempts) and set a career record for most pass attempts in a single season (508).

Prior to his move to Kansas City, Matthaei served three seasons under Chiefs Head Coach Andy Reid with the Philadelphia Eagles as the assistant to the head coach from 2010-12 after completing two seasons with the Eagles as a coaching assistant (2008-09).
