He received an offer from Notre Dame, then began preparing for finals, committed to the Irish, took his finals and then set off to South Bend, Ind., for his first trip to his future home.
The 6-foot-2, 195-pound Prosise is finally getting a chance to catch his breath after returning home from Notre Dame's campus Monday, and he spoke to IrishEyes.com about it.
"It was really nice," he said. "We toured the campus, we got tours, we got to meet up with the coaches, got to meet a couple of players. I got to talk to the director of admissions.
"It's definitely different because I'm committed, but it feels really nice because that's the place I'm going to play my career."
Until the weekend, Prosise's knowledge of Notre Dame's campus came via his online research and through the eyes of people he knows. That is no longer the case after he took in the rich history the campus offers, and it left Prosise feeling even more strongly about the school then before the visit.
"It was better than what I thought," he said. "I had high expectations, and it definitely exceeded my expectations that I had for it. There was so much stuff. The Golden Dome is nice, the chapel is nice. I think the lake was one of the most beautiful things. I went to the grotto."
Although Prosise met with members of the coaching staff, he did not see coach Brian Kelly, who was not on campus.
But while there he met with the coaching staff, and got a feeling for how he fits into the Irish's defense, and his preferred position is free safety.
"I definitely fit in as safety, but more like a quarterback in the defensive (backfield)," Prosise said. "I like roaming in the back. I'm able to see everything, control everything."
Prosise made 40 tackles and intercepted seven passes as a junior, and picked up an offer from the Irish on May 16. Immediately, he listed the Irish as his favorite, and 10 days later he committed.
"The academics are one (reason), because it's a great school," he said. "And then, probably, just great football tradition, and great tradition everywhere around the school.
"It took about a week for me to decide. There was a lot of thinking that I did. It was right before exams and I really wasn't doing much. I had a lot of time to think, and I felt like it was right."
A stress-free summer awaits Prosise, and the only thing he needs to worry about in the recruiting process is when he will take his official visit to Notre Dame.
"We're in the process of putting schedules together and see when we're going," Prosise said.
