Banks, who is ranked No. 33 overall by ESPN and No. 7 in Texas in the Class of 2022, had previously committed to Oregon, but he changed his mind Dec. 6 after coach Mario Cristobal left for the same position at Miami.
The 6-foot-5, 290-pound tackle from Summer Creek High School in Houston had taken visits to Texas and Texas A&M before his decommitment, and he had already established relationships with the Longhorns' coaching staff.
Banks becomes the highest-ranked commitment in the Longhorns' class with four days remaining until signing day. Steve Sarkisian and his staff have 14 ESPN 300 commitments, with six ranked in the top 150.
