Okotcha made the defection official on Wednesday by signing his letter of intent to the Sooners.
It was the second time Okotcha had changed his mind during the recruiting process. He committed to Wisconsin before the 2010 season began and switched to Notre Dame in November.
Okotcha and McDaniel highlight a class that led Coppell to one of its most successful seasons in school history. The Cowboys didn't lose a game until their heartbreaking 40-39 playoff loss to Euless Trinity in what may have been the best high school game of the year.
McDaniel rushed for 1,906 yards and 32 touchdowns in 2010. He also caught 40 passes for 492 yards and three touchdowns. He projects as a slot receiver at Notre Dame.
Quarterback Joe Minden, a late riser in the recruiting process who had his best games in the playoffs, signed with Stephen F. Austin.
