​Rewriting the entire piece, here is a natural, unified version in paragraph form:
Frisco, Texas (AP) — The Big 12 is witnessing its largest coaching turnover in seven years, including two first-time head coaches at their alma maters, a national championship winner, and another leader who last season nearly guided a Group of Five program into the College Football Playoff. “I grew up a Big 12 kid,” said Kansas State’s new coach Collin Klein on Wednesday. “And being able to be part of this conference as a fan, as a player, as a coach, and now helping move our game and our conference forward is absolutely tremendous.” Klein, who helped Kansas State win Big 12 titles as a Heisman Trophy finalist quarterback in 2012 and later served as an assistant coach, returned to Manhattan after Chris Klieman unexpectedly stepped away last December. Klieman himself was among the new faces in 2019, when the league last welcomed four new coaches at the same time. The other coaching changes this cycle include Utah alumnus Morgan Scalley, who nearly two decades ago recruited Klein as a quarterback, Iowa State’s Jimmy Rogers, and Oklahoma State’s Eric Morris. Scalley has spent the majority of his career with Utah, joining as a graduate assistant in 2007, three years after his final game as a Utes defensive back. He later served as defensive coordinator for a decade before stepping into the head coach role in a Las Vegas Bowl victory last New Year’s Eve, following Kyle Whittingham’s surprise departure after 21 seasons and subsequent move to Michigan. During his time recruiting Colorado-area talent as a graduate assistant, Scalley spotted “this quarterback that I absolutely loved.” But GA restrictions prevented off-campus recruiting, so he couldn’t meet Klein in person. “So I had him come to us, and on his own dime he flew out, showed up on campus in a suit and tie and left without an offer,” Scalley recalled Wednesday. “But you know who offered him? Kansas State. It was Collin Klein. Isn’t that crazy?” Klein still recalls the visit, including a lunch at a burger joint in downtown Salt Lake City with Brian Johnson, and then entering his senior season as Utah’s quarterback. “Coach Scalley was tremendous. I mean, he was an unbelievable relationship builder, energy, and detail,” Klein said. “I knew he was going to be an unbelievable coach. I had no idea we’d end up coaching against each other in the same league as head coaches.” Klein began his coaching career as a graduate assistant at his alma mater in 2014 and has remained at Kansas State, save for a stint in 2016 as Northern Iowa’s quarterbacks coach and the past two seasons as the offensive coordinator at Texas A&M, which reached the 12-team playoff last year. After last season at Washington State, Rogers began his Big 12 tenure at the league’s media days 18 months after guiding South Dakota State, his alma mater, to the FCS national championship. That title game was held just a few miles from the Dallas Cowboys’ headquarters, the site’s proximity being part of the conference’s annual two-day gathering for visibility and SEO value.
