Bob Stoops exits as Oklahoma coach after 18 seasons

— -- Bob Stoops, the longest-tenured coach in college football, has stepped down after 18 seasons with the? Oklahoma Sooners, he announced?Wednesday.

"After 18 years at the University of Oklahoma, I've decided to step down as the head football coach," Stoops said in a statement. "I feel the timing is perfect to hand over the reins. The program is in tremendous shape. We have outstanding players and coaches and are poised to make another run at a Big 12 and national championship.

"...?Thank you all for a lifetime of memories we shared together of 10 conference championships, the 2000 national championship, strong relationships with players and coaches, and the great Oklahoma football fans. Boomer!"

Stoops will be succeeded by 33-year-old Lincoln Riley, who has served as offensive coordinator for the past two seasons.?Stoops will remain as special assistant to the athletic director.

"The time is now because Lincoln Riley will provide a seamless transition as the new head coach, capitalizing on an excellent staff that is already in place and providing familiarity and confidence for our players," Stoops said in the statement. "Now is simply the ideal time for me and our program to make this transition."

Stoops said he did not base his decision on health reasons and that he's "had no incidents that would prevent me from coaching." A high-ranking Oklahoma athletic department official told ESPN's Gene Wojciechowski that Stoops' decision "was not an overnight revelation."?

The source added that Stoops' father, Ron, suffered a heart attack and died while coaching a high school game in Ohio in the late '80s and that Stoops has always had that in his mind. The source also said Stoops didn't want to get to the point at which the school forced him out, adding that he doesn't expect Stoops to coach again at any level.

"He didn't want to go from the sidelines to the graveyard," former Florida coach Steve Spurrier told ESPN on Wednesday. "He pretty much was able to go out on top."

Stoops joined the Sooners as a rookie head coach in 1999, and he guided OU to the 2000 national championship, 10 Big 12 titles and 14 seasons with double-digit wins, including an 11-2 mark in 2016.

Stoops, who turns 57 on Sept. 9, is the winningest coach in OU history with a 190-48 record (.798 winning percentage). He has gone 121-29 in Big 12 play and has taken the Sooners to bowl games in every one of his 18 seasons -- going 9-9, capped by January's 35-19 victory over Auburn in the Sugar Bowl.

His 190 victories rank fourth among FBS coaches, behind Brian Kelly (230), Bill Snyder (202) and Nick Saban (205).

In addition, he coached two Heisman Trophy winners: quarterbacks Jason White (2003) and Sam Bradford (2008).

"The Bible says, 'To everything there is a season, and a time to every purpose under the heaven,'" Stoops said in his statement. "I'm grateful for this season of my life, and feel I've fulfilled my purpose here at OU as its head football coach."

Stoops was finishing his third season as defensive coordinator under Spurrier at Florida when the Sooners came calling and hired him in December 1998.

Oklahoma had fallen into disrepair after three losing seasons under John Blake. When Stoops arrived, chicken bones littered the practice field, where fans had still been allowed to tailgate. Even more telling, the sign Bud Wilkinson put up coming out of Oklahoma's locker room, "PLAY LIKE A CHAMPION TODAY," was dilapidated and missing letters.

After only two seasons with "Big Game Bob" at the helm, Oklahoma was a national champion again, beating No. 2 Florida State 13-2 in the BCS National Championship Game at the Orange Bowl.

The Sooners would play for the BCS national title three more times under Stoops, losing to LSU (2003 season), USC (2004) and Florida (2008).

His 2008 team scored 716 points,?which at the time had been the most by any team in a season.

Stoops was named Walter Camp Coach of the Year in 2000 and 2003 and was named Big 12 Coach of the Year six times. He is the only head coach in the BCS era to have won the Rose Bowl, Orange Bowl, Fiesta Bowl and Sugar Bowl.

On Wednesday, Stoops took time to thank his players -- past and present -- and the fans.

"I'm especially thankful for being able to coach so many talented young men over my 18 years here," Stoops said. "It has been so rewarding to see these players come to OU and mature over a four or five-year career, and not just on the field. To play a small part in their growth is what I will always cherish the most.

"None of my success would have happened without the best fans in the country. I can't tell you how much I appreciated the 110 consecutive home sellouts. The passion of our fan base is unmatched, and their support has played a huge role in not only home games, but road games and all 18 of our bowl games, as well."

Iowa coach Kirk Ferentz, who was hired by the Hawkeyes just one day after the Sooners hired Stoops, becomes the new longest-tenured coach in the FBS.

Over the years, Stoops' name has been attached to many college and NFL coaching vacancies. Each time, however, Stoops chose to stay with the Sooners.

"I'm thankful that my career at Oklahoma was marked with consistent leadership in President David Boren and Director of Athletics Joe Castiglione," Stoops said. "It's extremely rare in college athletics to have no change in these leadership positions over a nearly 20-year span. I always appreciated the way both of them supported me and our program. They both played an enormous role in all our successes."

Stoops attended the University of Iowa and was a four-year starter at defensive back. His first coaching position was as a volunteer coach and graduate assistant for the Hawkeyes. That was followed by assistant coaching positions at Kent State, Kansas State and Florida, where he was part of the Gators' national championship team in the 1996 season.

Stoops is part of a coaching family. His brother Mike is the Sooners' defensive coordinator and was head coach at Arizona from 2003 to 2011. His brother Mark has been head coach at Kentucky since 2012, and his brother Ron is special teams coach at Youngstown State.

Stoops also groomed several assistant coaches who moved on to bigger things, including Mike Leach (Washington State), Kevin Sumlin (Texas A&M), Bo Pelini (Youngstown State) and Jay Norvell (Nevada).

Stoops, who has two sons who play high school football and are entering their senior year, said he and his wife, Carol, plan on staying in Norman, Oklahoma.

"The coaching life is like a relay race, and I'm thankful for my turn and am confident as I pass the baton," Stoops said. "Carol and I intend on staying in Norman -- it is our home. I will be available to Coach Riley and the athletic department in any manner."

"Bobby is ready to go to the beach and watch his kids play ball," Spurrier told ESPN. "He's had a wonderful career. He knew when enough was enough."

Riley, who won the Broyles Award as the nation's top assistant coach in 2015, will become the youngest head coach in the FBS.

"I'm sincerely honored to be given this opportunity to be the head football coach at the University of Oklahoma," Riley said in a statement. "I want to thank Coach Stoops for bringing me here two years ago and making me part of the Sooner family. He is one of the greatest coaches in the history of the game, at any level. I'm absolutely thankful for our friendship and for the mentorship he has provided.

"Coaching at Oklahoma is a dream come true for me and my family. ...?I look forward to continuing the tradition of excellence that Coach Stoops and so many others before him have instilled in this great program."

The Sooners have fared well with Riley as offensive coordinator. During his two seasons at OU, the Sooners are one of just two FBS teams -- along with TCU -- to average more than 300 yards passing (313.1) and 200 yards rushing (229.4) per game.
