He also understood why the Irish coaching staff made Saturday's primetime kickoff against USC was turned into a recruiting extravaganza.
"It was nice. It was a huge game, a lot of people and lots of enthusiasm," the 6-foot-2, 195-pound class of 2013 star said. "And it was a good atmosphere. I was there for the Michigan State game. It was totally different, almost uncomparable. It was totally different. You could tell how big this game was."
Isaac, who holds offers from the likes of Michigan, Iowa, Illinois and Northwestern in addition to one from Notre Dame, said the day was about experience a huge event at Note Dame, and how the program can shine at such a time.
"I won't say that I learned anything," Isaac said. "It was just good to see how people react to these games. You want to see school recruitng you to win, but it's not going to affect my decision."
Isaac's day began early when he arrived on campus.
"I went around campus and went on the tour," said Isaac, who talked about what stood out. "The amount of people around football and how important it is to everybody …that was something." Isaac made the journey to South Bend, Ind., the morning after he ran for 190 yards and two scores on 22 carries in a 56-51 loss Marist.
He spent time speaking with assistants Chuck Martin, Kerry Cooks and Tim Hinton as well as coach Brian Kelly.
"They just (were saying) they want me there as a running back and they want me to know they want me there," Isaac said. "I want to take my time with this one. I have the playoffs so I'm not sure (about another visit), but if I get time off, I may make one. But if I make one, I don't even know where it would be to."
Isaac said if he does make another visit during the season, it would likely be to Michigan or Iowa.
