Henson earned the reputation as one of the most tenacious recruiters in the Southeastern Conference during a four-year stint on Les Miles' staff. LSU most recently had the No. 1 national recruiting class ranked by ESPNU in the Class of 2009.
Henson replaces Dave Christensen on Gary Pinkel's staff and becomes the first new coach added to his staff since the group arrived from Toledo in 2001. Christensen was recently hired as Wyoming's new head coach.
Henson, 33, played at Oklahoma State and served on Miles' staff with the Cowboys before moving with him to LSU.
"I am very excited to join Coach Pinkel's staff and work with this program, which is really well-respected nationally," Henson said. "Missouri's staff has a reputation of doing things in a first-class manner, and the strides they've made over the years makes this a very attractive place to be. I'm grateful for the opportunity and pleased to be back in Big 12 country."
His hiring is expected to boost Missouri's national reach in recruiting. The Tigers have won back-to-back North Division championships but have largely done that with a formula of home-grown players from Missouri and under-recruited players from Texas like Sean Weatherspoon, Stryker Sulak and Ziggy Hood.
