And Midland coach Eric Methner said the Irish are getting a great player, and an even better individual.
"He's a super kid, extremely strong work ethic, he's an outstanding young man," Methner said. "He's a better person than he is a football player, and he's a heckuva football player. He's a quality kid, tremendous work ethic and comes from a great family."
The 6-foot-6, 297-pound Elmer plays right tackle at Midland because there is a three-year starter at left tackle. But he could move to left tackle as a senior.
"He can play anywhere we wanted him to play. He's an outstanding kid and a great player," Methner said. "He's a good player. He's a 6-6, 300-pound right tackle that runs well, moves well, is constantly working on playing with a lower pad level. He practices hard and plays well in the game. He knows the areas he has to work on maintain to be a good player.
"He has a nice combo of strength and speed. He has good feet for a big man, great speed. He's a 5.19(-second) 40 guy. He's far from a finished product he knows that. He's played four games his junior year in high school. He's a hard worker and knows what he needs to improve."
The football field isn't the only place Elmer succeeds.
"He's just an awesome person," Methner said. "He's humble respectful, taking all advanced placement classes. He's extremely bright. The teammates think work of him, coaches think the world of him."
"I think in his heart he felt Notre Dame was the right fit for him, academically," Methner said. "He's extremely bright and he liked all the things Notre Dame encompassed."
