One of the longest-tenured head coaches in college football is stepping down.
Per Bruce Feldman, Bob Stoops is retiring as Oklahoma's head coach, effective immediately.
The 56-year-old Stoops led Oklahoma to the 2000 national title and took the Sooners to 10 Big 12 titles, including in each of the past two seasons. He won Big 12 coach of the Year honors six times. The Sooners went 60-30 (.667) against AP Top 25 foes during his tenure—the highest winnning percentage against ranked teams of any school during that stretch. His teams also went 25-11 against its two biggest rivals (14-4 vs. Oklahoma State and 11-7 against Texas).
Offensive coordinator Lincoln Riley, who joined Oklahoma's staff in 2015 and promptly won the Broyles Award as the nation's top assistant, will take over for Stoops.
