SAN FRANCISCO, CA – Soon after the departure of Jim Harbaugh, the 49ers moved quickly to bring in former Jet’s head coach, Rex Ryan. Ryan brings a hefty amount of experience and enthusiasm with him that will benefit a successful organization looking for a quick turnaround. Ryan will primarily handle defensive duties, along with the newly acquired defensive coordinator, Teryl Austin. Austin’s recent stint in Detroit resulted in him transforming the Lion’s defense to be one of the top in the league. Ryan will leave the offensive duties to Rob Chudzinski, a veteran offensive mind with experience molding an offense to fit its players skill sets.
