NORMAN — He hasn't gotten on the field for an official game, but Oklahoma redshirt freshman linebacker Jon-Michael Terry has been one of the most talked about players throughout the spring season. Baker Mayfield even brought up Terry during the Heisman weekend, saying that he was one of the scout players who impressed him the most. Lincoln Riley later echoed his quarterback, picking Terry as one of the young players with a bright future — a label Terry began fulfilling with a strong spring showing. With positions up for grabs in the new 4-3 defense, Terry is primed to be a key contributor in the upcoming season.
