Greg Knapp, longtime NFL assistant coach, dies after being hit by car
Knapp, 58, had joined the New York Jets as a passing game specialist in January after spending years as a quarterback guru and play-caller around the league.
He previously was a quarterbacks coach or an offensive coordinator for an NFL team every year except one between 1998 and 2020, working for the 49ers, Falcons (twice), Raiders (twice), Seahawks, Texans and Broncos.
Before joining the 49ers staff as an offensive quality control coach in 1997, Knapp spent nine years on the coaching staff at his alma mater, Sacramento State.
"Greg had such an inner peace about him that people always seemed to gravitate towards," Jets head coach Robert Saleh told the team's website.
"He lived life in a loving way that helped him connect with people from all walks of life in a unique way. In his short time here, I believe the people in this organisation had a chance to experience that connection."
The Jets had entrusted Knapp with preparing the second overall pick in this spring's NFL Draft, Zach Wilson, for life in the NFL.
Knapp previously had worked with numerous star quarterbacks including Steve Young, Peyton Manning, Michael Vick and Matt Ryan.
During the Jets' minicamp last month, Knapp had told reporters he found it "invigorating" to work with a young talent like Wilson.
"It is really cool," Knapp said then. "Both my parents are teachers. It's like, here's the canvas, start teaching them what you know without overteaching them too quickly. So that's the challenge, but it's really exciting."
Knapp is survived by his wife Charlotte and daughters Jordan, Natalie and Camille.
