No. 17 Notre Dame will be counting on freshmen at key positions Saturday when it opens the season against Rice without four players who are still being investigated for possible academic dishonesty. Cornerback KeiVarae Russell, receiver DaVaris Daniels, defensive end Ishaq Williams and backup linebacker Kendall Moore remained on the roster handed out this week, but were not included on the depth chart. The depth chart has six freshmen and six sophomores on the two-deep on defense.
