AUSTIN, Texas — The former athletic director at Baylor University alleges that regents schemed to make black football players scapegoats for a decades-long problem of sexual assault at the nation’s largest Baptist school, and that he resigned rather than be part of a massive cover-up.

Ian McCaw said he was “disgusted” by the racism and the “phony” investigation document that Baylor issued in 2016 that leveled findings against the football program, according to excerpts from his June 19 deposition. He said he ultimately resigned because he “did not want to be part of some Enron cover-up scheme.”

The excerpts appear in documents filed Wednesday by attorneys representing 10 women who are suing Baylor.
