Bob Simmons, longtime Oklahoma State head coach who bridged the Big 8 to the Big 12, dies at 77

Bob Simmons, a former Oklahoma State Cowboys football head coach who navigated the program through a major conference transition, has died at 77. Simmons coached OSU from 1995 to 2000, the years that included the dissolution of the Big 8 and the formation of the Big 12. Multiple outlets reported his death Tuesday, and Oklahoma State posted a remembrance on its official social media channels without providing a cause of death.

Simmons took over a team that had been through six straight losing seasons, and his early tenure reflected the challenge of rebuilding in an unstable competitive landscape. The Oklahoman reported that he inherited those conditions and that NCAA probation-related effects still lingered during the period, a factor that shaped roster and program momentum. His first season ended with a 4-8 record, and OSU went 2-5 in Big 8 play, according to The Oklahoman’s reporting.

When the league realignment finalized, Oklahoma State became part of the Big 12, which immediately raised the visibility and stakes of every conference decision. Simmons’ most prominent run came in 1997, when The Oklahoman said he was named Big 12 Coach of the Year after guiding the Cowboys to an 8-4 season and a berth in the Alamo Bowl. That bowl appearance was described as Oklahoma State’s first since 1988, marking a renewed sense of direction during a decade when the sport’s expectations were hardening.

The mid-to-late Simmons years, however, also carried the reality that rebuilding does not always produce smooth sequences. After the 1997 high point, Oklahoma State’s results slipped into a difficult stretch, and, per The Oklahoman, Simmons resigned under pressure. He was later replaced by offensive coordinator Les Miles, a change that indicated OSU was looking for a different operating style as the Big 12’s arms race accelerated.

Simmons’ football background extended beyond his Oklahoma State head-coach role. Before OSU, he was a coach at the University of Colorado under Bill McCartney during the era that included Colorado’s 1990 national championship. Sports Illustrated and The Oklahoman noted that Simmons served as an outside linebackers coach, with additional defensive-line responsibilities, before moving to Stillwater in 1995 to replace Pat Jones. That continuity within high-level college programs helped shape the defensive identity Simmons emphasized while running OSU.

The Oklahoman also reported that Simmons left a mark through recruitment and staff decisions that affected the program’s longer-term growth, and later OSU leadership built around momentum that followed his departure. Sports Illustrated and The Oklahoman both connected Simmons to the era’s talent pipeline and noted that he remained involved with football in Oklahoma State’s orbit after stepping down, including a reported stint as a quarterbacks coach in 1995.

In reflecting on the job’s pressures, Simmons told The Oklahoman in a 2017 interview that he understood the business side of college football and that winning was followed by inevitable ebbs and flows. He said, “I created an atmosphere of winning, but understood there were going to be ups and downs in the process,” and described a broader national shift toward what coaches can do “lately.” With his death now reported, former players and coaches are likely to revisit what his six years at OSU meant in the Big 12’s earliest form and how the transition from the Big 8 era reshaped expectations for the program.
