Vance Joseph is back in the mix for head coaching jobs. The Broncos’ defensive coordinator received a request Monday to interview for the New York Jets’ vacant head coaching job, sources confirmed to The Post. Joseph, 52, is in his second season coordinating Denver’s defense and has orchestrated one of the best units in the NFL this fall. The Broncos finished third in scoring defense, second in yards per play allowed, second in net yards per passing attempt allowed, and second in rushing yards per attempt allowed.
