Walker, a cornerback, stands out as the most significant loss for the Oklahoma Sooners’ defense among a trio of players departing. Having transferred from Louisville, Walker spent three seasons in Norman and became a key figure in the secondary. This season, he played in all but one game as a redshirt junior, logging the second-most snaps in the defensive backfield behind only Eli Bowen.

Throughout the season, Walker recorded 24 tackles, seven pass breakups, and an interception. He had also started three games the previous year, solidifying his role as a trusted defensive asset.
In contrast, the departures of Vickers and McCarty are less impactful and likely to be forgotten over time. Vickers, a cornerback, had a promising freshman season but faced significant setbacks this year. He was arrested in June for DUI and possession of marijuana, which led to disciplinary action from the team, though it was handled privately.
Vickers missed the first three games of the season and played in only four overall, limiting his impact. However, since he appeared in fewer than five games, he will be able to redshirt this season and retain eligibility for future seasons.
McCarty, a safety from McAlester, Oklahoma, was another defensive player who struggled to find playing time. He played in just one game during his tenure with the Sooners and, as a result, his departure has had little impact on the team’s defense.
Together with Jayden Rowe, Walker, Vickers, and McCarty represent the defensive backs Oklahoma has lost to the transfer portal this year. While the departures of Vickers and McCarty may not leave a significant void, Walker’s exit will certainly be felt, given his consistent performance and leadership in the secondary. His loss, in particular, could be a challenge for the Sooners as they look to maintain their defensive strength moving forward.
