He was also made to feel pretty darn special when he was summoned along with a handful of other recruits to speak with Irish coach Brian Kelly.
"That was my first time at Notre Dame. It was a real good game," the 6-foot-6, 235-pound Charlton said. "The fans were going crazy, the coaches were showing me a lot of love. It was a great visit."
The star-studded day included the impromptu meeting with Kelly before the game.
"There were about six of us (from the 2013 class) who were picked out to go meet coach Kelly and talk to him," Charlton said. "It was good. He's a real good coach, so it was special. It was just general stuff of how much they like us at Notre Dame, and how special we were that they brought us over to meet him.
"Everything was real good. The coaches came over and talked to me a lot, and (assistant) coach (Tim) Hinton and (assistant) coach (Mike) Elston. It was a good experience."
Charlton already took unofficial visits to Michigan and Ohio State this season, and may return to Michigan for the Ohio State game in late November, but Notre Dame's campus was not the same as the others.
"They showed me around the whole campus," Charlton said. "It was a little different than anywhere I've been to, but not in a bad way. It was a little different."
There were also a few things that stood out to Charlton.
"The statistics of it, the graduation rate and stuff like that, and life after football and the people that went there," he said. "Also, how much the fans care about football, and how much they love it."
Charlton holds verbal offers from Cincinnati, Michigan, Purdue, Syracuse and UCLA.
