The Cardinals have announced Donnie Henderson's hiring as secondary coach, a name that's somewhat out of the blue.
Henderson has been working as a volunteer on Dennis Green's staff for the UFL's California Redwoods. It is possible Henderson's volunteer status allowed him to continue receiving compensation from the last NFL team that employed him.
Jacksonville fired Henderson after the 2008 season, his only season with the team. I can find no direct connections between Henderson and other members of the Cardinals' defensive staff, but Henderson has lived in Arizona and he spent the 1992 through 1997 seasons at Arizona State. Henderson and former 49ers coach Mike Nolan worked on the same defensive staff in Baltimore. Nolan and current Cardinals defensive coordinator Bill Davis subsequently worked together in San Francisco.
Another coach I spoke with described Henderson as a coach who isn't afraid to challenge players.
Like quite a few NFL assistants, Henderson has bounced from job to job. He was with the Ravens from 2000 through 2003 before spending two seasons with the Jets and one apiece with the Lions, Bengals and Jaguars.
Henderson replaces Teryl Austin, who left to become defensive coordinator at Florida.
