Rex Ryan, who hasn’t coached in the NFL since 2016, is shaping up to be the top candidate for the Denver Broncos’ defensive coordinator job, NFL Network reports.

Sean Payton became the new head coach of the Broncos after sitting out the game last season.

He’s tasked with reinvigorating a team that was supposed to make noise in the AFC West with Russell Wilson on board. Instead, the Broncos finished with a 5-12 record.

First, Payton must assemble his coaching staff, and Payton appears to be looking to Ryan to fill the defensive role.
