In this March 22, 2017, photo, Notre Dame defensive coordinator Mike Elko runs drills during NCAA college football practice in South Bend, Ind. Elko, the 39-year-old hired from Wake Forest this offseason, has taken his Fighting Irish players into something of a time machine, harping on the basics early instead of scheme as the defense looks to rebound from a nightmarish 2016 that saw its previous coordinator lose his job in the season’s first month.
