Head coach Todd Bowles and the Jets have promoted John Scott Jr. from defensive quality control coach to assistant defensive line coach, have hired David Diaz-Infante as assistant offensive line coach, and have brought in Tim Atkins to fill Scott's role as defensive quality control coach.

Scott came to Bowles' staff last year and entered the NFL for the first time after serving as a college coach for the past 12 seasons. Among the schools he coached defensive line or outside LBs with were Louisiana–Lafayette — where he earned his master's in education — and his most recent stop at Texas Tech. He played four seasons at DE at Western Carolina and two seasons for the Greensboro Prowlers in arenafootball2.

Diaz-Infante comes to the Jets after a stint in 2013-14 as an offensive assistant with the Arizona Cardinals, where he worked with Bowles. He had a long career as a guard/center in the NFL (Chargers, 1987, Broncos, 1996-98 and '01, Eagles, 1999), WLAF (Frankfurt, 1991-92), CFL (Sacramento, 1993-94), and XFL (Las Vegas, 2001), earning two Super Bowl rings with the Broncos.

Following his playing days, he was a TV studio analyst with FSN Rocky Mountain in 2003-04 before joining ESPN in 2004 as a college and high school football analyst. He also served as an analyst for the Broncos radio network from 2005-08.
