The filing by the California attorneys representing former player Brandon Vandenburg is the first hint the university's football staff might have some involvement in the incident, The (Nashville) Tennessean reported Wednesday.
Prosecutors had not given them a "large amount" of evidence, the attorneys said in their filing. Some of the 57 evidence CDs and DVDs were defective, and they had not gotten other forms or "text messages from witnesses and coaches."
The defense attorneys also challenged a "gag order" they said prevented them from hiring their own investigators and building their defense.
Vandenburg, 20, of Indio, Calif.; Cory Batey, 19, of Nashville; Brandon Eric Banks, 19, of Brandywine, Md.; and Jaborian McKenzie, 18, of Woodville, Miss., are charged with raping an unconscious 21-year-old student inside Vandenburg's dorm room on June 23.
