Two Big 12 schools among four vying for Air Force guard AJ Walker

AJ Walker, a guard who averaged 11 points per game last season for the Falcons, has cut his list to just four schools per CBS's Jon Rothstein. Walker will choose between Texas Tech, TCU and Tulsa, as well as the possibility of a return to Air Force, per Rothstein. If Walker elects to transfer, he will be forced to sit out next year and have two years of eligibility remaining.
