SOUTH BEND, Ind. (AP) — No. 10 Notre Dame is counting on a better running game this season. Last season, injuries to running backs Tony Jones Jr., Jafar Armstrong and others cropped up. Notre Dame averaged just 179.2 rushing yards. This season, speedy sophomore Kyren Williams and freshman Chris Tyree are atop the depth chart ahead of Armstrong and Jahmir Smith and C'Bo Flemister. Coach Brian Kelly says he's never had that kind of depth at the position. The Fighting Irish open the season Saturday at home against Duke.
