Heading into the 2019 season, Oklahoma State returns its two starting corners from a year ago in A.J. Green and Rodarius Williams. These two veteran players have a chance to be one of the best cornerback duos in the Big 12 next season. However, behind them, the Cowboys don’t have much depth and experience at corner. Texas A&M transfer Kemah Siverand and redshirt senior Bryce Balous saw some action in 2018, but outside of those two, no other cornerbacks on the roster have logged much college level playing time. And former corner Tanner McCalister, who rotated in some last season, has now converted to safety.
