As Robert Saleh said he planned to infuse every aspect of the Jets with a clear identity, the team on Thursday formally announced the bulk of the staff that will support him as he begins his first season as the head coach of an N.F.L. team.
Several of the assistants have ties to the San Francisco 49ers, whose defense thrived with Saleh as its coordinator over the last four years. The Jets’ defense, which ranked 26th in points allowed in 2020, will be led by Jeff Ulbrich, who was promoted to the Atlanta Falcons’ co-defensive coordinator this season after serving as their linebackers coach since 2015.
