Huggins and other high school recruits cannot sign until Feb. 6.
Offensive line has been an even bigger concern for the Sooners.
San Antonio high schooler Matt Beyer and Tulsa Union’s Dalton Rodriguez once gave OU a pair of commitments there, but Beyer’s football career ended because of injury and Rodriguez recently switched his commitment to Tulsa in part so he could stay on the defensive side.
St. John (6-6, 305) picked the Sooners over Kansas. He also had offers from Oklahoma State, Texas A&M, West Virginia, Oregon State and Arkansas among others.
Daimler (6-6, 270) had been committed to the Sun Devils since October but announced late in the afternoon on Twitter that he had withdrawn his commitment. A little more than three hours later, he announced that he’d committed to the Sooners.
Daimler also had offers from Colorado, Colorado State and Washington State among others.
Kicker/punter Jed Barnett of Laney Community College also signed Wednesday.
Barnett originally went to California out of high school.
Barnett averaged more than 50 yards per punt in high school.
The Sooners missed out on at least one other target Wednesday, when tight end Emmanuel Bibbs stuck with his original commitment and signed with Iowa State despite a late push from Oklahoma.
