In a mild shock to Mizzou fans, longtime assistant David Yost has resigned as the offensive coordinator and assistant head coach.
A 12-year veteran of Gary Pinkel's system, Yost first got his start as the quarterbacks coach and recruiting coordinator.
By bringing in a succession of players like Brad Smith, Chase Daniel and Blaine Gabbert, he cemented his status as a master recruiter.
In 2009, he was promoted to offensive coordinator after Dave Christenson bolted for Wyoming's head coaching gig. In the years that followed, he built an offensive juggernaut that was both balanced and efficient, raking in over 400 yards every year.
His pinnacle of achievement was in the 2011 season, where he made first-year starter James Franklin one of the nation's most dangerous dual-threat quarterbacks. Diminutive Henry Josey became the featured back in a balanced offense that was one of two to average 230 yards passing and rushing, according to ESPN.
That would all change with the Tigers' move to the SEC.
But where the Tigers will miss him the most is his recruiting ability.
While Missouri has consistently boasted a strong team, they never have had a hotbed of talent to choose from. Yost was one of the big reasons that Mizzou was able to make do with what they had. He was one of the main reasons star recruits Dorial Green-Beckham and Maty Mauk chose to come to Columbia.
Should the Tigers promote from within or hire from outside?
Spring practice yielded a devastating shoulder injury to starter James Franklin, one from which he would never fully recover.
As the season progressed, more and more injuries to the offensive line caused back ups and redshirts who would usually never see the field to compete against the top defenses in the nation.
Franklin was almost never healthy (shoulder, leg, concussion) and untested Corbin Berkstresser was thrown to the wolves. In what many consider his only disappointing season, Yost had failed to come through.
Sure he had plenty of reasons: Injuries, suspensions, brand new defenses, lack of talent, you name it and Missouri probably had it. Part of the reason that this loss is shocking is that fact that he had been loyal to Pinkel ever since their days at Toledo when he was a grad assistant.
According to Twitter, Gary Pinkel asked Yost to give it a week and reconsider before he made his final decision.
While he may have frustrated Tigers fans with his puzzling calls and odd personnel choices, he was always considered a premier coordinator and a brilliant recruiter.
This might be a huge loss of the Tigers, but it can be looked as a way to improve. There are plenty of quality choices to be his replacement, and that may be the jump that Missouri needs to truly become an SEC powerhouse.
