He returned in 2018 to coach Matt Ryan and Matt Schaub and was praised by both veterans for his work in the quarterback room, and when Dan Quinn and Dirk Koetter left, Knapp took on a job as the New York Jets quarterbacks coach and the man who was to be responsible for developing #2 overall pick Zach Wilson.
