IOWA CITY, Iowa – Seth Wallace has coached the Iowa linebackers since 2016, and during that time, he has helped Josey Jewell achieve stardom and helped to install a new 4-2-5 formation that is now in Iowa's DNA, according to head coach Kirk Ferentz.

Wallace met with the media on Tuesday and talked about the new 4-2-5 scheme and about the challenge of finding somebody to replace Amani Hooker, who declared for the NFL draft as a junior.

Hooker played a dual role as a linebacker and defensive back in the 4-2-5 alignment, and he played it at an exceptionally high level to where he is now preparing for the 2019 NFL Draft instead of for his senior season at Iowa.

Wallace mentioned senior Michael Ojemudia and redshirt freshman D.J. Johnson as being candidates to fill Hooker's vacated role on defense.

Wallace also talked about the decision to move Amani Jones from linebacker to defensive end and about the progress being made at linebacker this spring.
