Nebraska plucked a prize from old rival Oklahoma on Wednesday, inking wide receiver Cortez Mills on early National Signing Day.Mills committed to Oklahoma on July 1. He decommitted on Wednesday, then signed with the Cornhuskers. Mills, from Homestead (Fla.), told On3 that the Nebraska recruiting staff didn’t let him forget he was wanted.”Nebraska never went away,” said Mills, who is ranked No. 15 at wide receiver by the 247Sports composite. “They stayed consistent with me. They showed me that I was a top priority for the program and that they really wanted me. How they stayed consistent and true to who they are was very important in my decision.”The Nebraska coaches never let their foot off the brake. They recruited me, my mom, my sister, we all had a bond and that love meant something. We made the decision as a family that Nebraska is best for me.”–Oklahoma pulled off a flip of its own, signing quarterback Jett Nieu, a three-star prospect from Lehi (Utah) High School.He had been committed to Oklahoma State since Sept. 10. According to 247Sports, it was new Oklahoma offensive coordinator Ben Arbuckle — with whom Niu has built a relationship during the recruiting process — who lured him to the Sooners.
