Caleb Hackleman is a developing 6-foot-6 OSU tackle with upside and a long runway
Hackleman is a redshirt sophomore offensive lineman at Oklahoma State in the 2026 season, and the big story is projection: at 6-foot-6 and 298 pounds, he brings the frame coaches want, plus the multiyear development path that often turns raw linemen into dependable starters. Oklahoma State describes him as a “developing prospect,” and his high school résumé shows power-sport traits—shot put success, academic discipline, and experience in a run-heavy offense. He has not yet logged college game snaps, so the appeal is upside, not production.
