Former Texas Tech commit James Castleman (Amarillo, Texas, Amarillo) is now headed to Oklahoma State. "I am now headed to the Cowboys," Castelman said. "The bottom line is that I just felt more at home with Oklahoma State. They have a great environment. If I took football out of the equation that's where I knew I wanted to be. It's a better place and the total package. And their facilities are amazing." The 6-foot-4, 275 pound defensive end prospect originally committed to Tommy Tuberville and the Red Raiders back in April.
