SOUTH BEND, Ind. — Aneyas Williams sprinted between Notre Dame’s practice fields on Friday morning, out of habit and intention. The junior running back is in a hurry, no longer blocked from the field by the two first-round picks. And Williams knows he might as well get extra conditioning when he can, creating habits for the rest of Notre Dame’s running backs at the same time.Williams will try to replace Jeremiyah Love and Jadarian Price, an impossible task everywhere but inside the running back’s own head. Williams played just six games last season after suffering a serious right elbow injury in training camp. He was never right, playing just 47 snaps and logging only 24 carries, even though they went for 224 yards and five touchdowns.No one really noticed, not with Love and Price in the backfield.Still, Notre Dame didn’t go into the portal last winter, happy with its running back hand where Williams might be an ace, even after winter surgery to repair a partially torn triceps and clean up the elbow. He enters training camp as Notre Dame’s starter without the Irish acknowledging it. But it appears that time is coming soon.“He may be the most confident kid I’ve ever been around. And that’s rare,” said running backs coach Ja’Juan Seider. “The kid earned the right to play. And that’s what (we) like about him.”At first glance, Williams’ confidence might seem underserved considering how little he’s played. Yes, there was that 36-yard catch to help beat Penn State in the Orange Bowl, with Seider on the other sideline. “One of the biggest catches ever,” Seider said. “Sent my ass home crying.” And yes, he averaged 9.3 yards per carry on last season’s limited work, which would have ranked second nationally if Williams had appeared in three more games. But Williams played just one snap against Miami. He didn’t play against Texas A&M or USC, the only other high-stakes games on the schedule.
