The one that came earlier this month from Notre Dame.
"She was happy about it," Pat Muldoon said. "She wants to know what my thoughts were on them. We talked for a little bit.
"My grandma is a pretty big fan. She is just catholic, so she just likes Notre Dame. She knows it's my decision, but she'd like me to go there. Her and my grandfather were pretty big Notre Dame fans."
On the other side of the family, the four-star defensive end from St. Xavier High in Cincinnati, Ohio, has loyal Ohio State fans and alum. Muldoon has two uncles and a cousin that have suited up for the Buckeyes. On top of that, his father played offensive line at Ball State, and his other grandfather was an offensive lineman at Louisville.
The family ties are everywhere, and the scholarship offers have come from all over the country. Muldoon is sporting free rides from the likes of Ohio State, Wisconsin, Iowa, Michigan State, Pittsburgh, Penn State, Stanford and Louisville.
Muldoon still hasn't told all the programs that have offered him, that he is no longer considering them, so he doesn't want to go public with his list of favorites. However, Notre Dame is indeed in the running for Muldoon's services, and he will visit the campus with his mother on Saturday.
"Just to learn more about the school and try and rank them above other schools I've seen, see where they stand and what they have to offer," Muldoon explained. He will check out Purdue on Friday, and he's already previously visited Ohio State, Wisconsin, Iowa, Michigan State, Cincinnati, Louisville and Pittsburgh.
Muldoon has been to Notre Dame before, for a game against Pittsburgh. He just doesn't remember much about the trip.
"The academics is a big factor," Muldoon said of why he is considering Notre Dame. "They're a top academic school. They're relatively close, and a pretty prestigious program."
This past season, Muldoon helped lead St. Xavier to a state championship with 75 tackles, 12 sacks, an interception and two forced fumbles. During the season, he played at 6-foot-4, 225 pounds. Muldoon says he is currently up to 240 pounds now.
"I think I've gotten faster," he said. "Last time I benched, it was 265, and now it's 345. My squat was 375, and now it's 485."
Muldoon has been keeping in touch with Irish defensive coordinator Corwin Brown, and linebackers coach Jon Tenuta through email.
"They did say that their style of defense will fit my style of play really well, but they haven't gone into a whole lot of detail," Muldoon said.
These trips this weekend are the first two of the summer for Muldoon. He hasn't scheduled any other visits to date, and he'd like to still make his college decision before his senior season.
"But with all the schools right now, it's going to be tough to make that decision," Muldoon said.
Muldoon thinks that his grandmother has been to Notre Dame before, but you can bet if he decides to suit up in an Irish jersey, she'll be making a return trip.
