Oklahoma State assistant Mike Boynton Jr. has been promoted and will replace Brad Underwood as the Cowboys head coach.
The school made an official announcement Friday afternoon.
Boynton came to Stillwater with Underwood a year ago, after spending three seasons with him at Stephen F. Austin. Oklahoma State went to the NCAA tournament this past season and the Lumberjacks went to the tournament all three years that Boynton was an assistant.
"At the end of the day, we view coaching from the same perspective," athletic director Mike Holder said in a statement. "All of the qualities that I value resonate in him. He said one thing that really stuck with me, that coaching is about leadership and family, and I agree with that wholeheartedly. I know I'm proud to have him as the leader of our basketball program, and think once people get to know him they'll feel the same way."
Underwood, who was second to Kansas' Bill Self in Big 12 Coach of the Year voting, left earlier this month to take the head-coaching job at Illinois.
Boynton was also an assistant for four seasons at South Carolina and played for the Gamecocks in the early 2000s.
Boynton might have a depleted roster. All-Big 12 point guard Jawun Evans has announced he is entering his name in the NBA draft. The team's No. 2 scorer, Jeffrey Carroll, announced Friday he will enter his name but won't hire an agent for now, meaning he could return.
"At this time, I think I would be silly to not test the NBA waters and seek the advice of actual NBA personnel, but I will do so without hiring an agent," Carroll said. "If their advice is that I return to college for my final year, I will proudly put on that Cowboy jersey and give my all for Oklahoma State."
Shooting guard Phil Forte's eligibility is up after one of the most productive careers in school history.
Still, Boynton sees potential.
"Oklahoma State is one of the premier basketball programs in the country," Boynton said. "To have this opportunity given to me by Coach Holder and the OSU administration is something I could have only dreamed of. I'm very thankful and grateful to the players here, to the guys that I have played and worked with throughout my life, and to the Oklahoma State family for welcoming me and my family over the last year."
Former Oklahoma State player Doug Gottlieb on Friday said on his radio show that he was no longer a candidate for the Cowboys' men's basketball head-coaching job.
Gottlieb has worked for ESPN and CBS, and he recently agreed to a deal with Fox. He does not have any college coaching experience, but sources told ESPN earlier this week that athletic director Mike Holder was intrigued by Gottlieb and his potential.
Oklahoma State went through an up-and-down season in Stillwater. After starting 10-2, the Cowboys endured a six-game losing streak to open Big 12 play before turning things around with 10 wins in 11 games. The season finished on a sour note, with two straight losses to finish the regular season, plus losses in their first game of the Big 12 and NCAA tournaments.
The Cowboys were a top-10 team in scoring during the regular season, averaging 85.5 points.
