Shepard, who attends Fresno (Calif.) Washington Union High, said one of the things that concerned him was when he was told by one of Notre Dame's deans he may not be able to gain January admittance because he needed more math classes.
"They said I may need four or five math classes, and that is not what they told me (before)," Shepard said. "The visit was cool, even though we lost. But when they gave me that plan, it turned me down. That was my whole plan and they said I need another semester of high school. I can't do that."
After committing to Notre Dame in March, Shepard transferred from Fresno Central East Campus to Washington Union so he could take the necessary classes and graduate early.
The transfer also cost Shepard his senior season as the CIF (California's governing body for high school athletics) ruled he was ineligible after the transferring. He lost subsequent appeals.
The 6-foot, 175-pound Shepard, who is the third-rated cornerback in Scout.com's 2012 class, was uncertain which schools he would look at now.
"I'm going to graduate in December," Shepard said. "Right now I have no clue what I'm going to do. I'm just going to keep looking at other schools."
He said the game against USC was enjoyable.
"Everyone was disappointed that we lost," Shepard said. "We were on the sideline a little bit, and after that we just all went to the stands and were watching it."
Shepard did spend some time with the Irish coaching staff, and he was told how much the program needed him.
"They were telling me they need me here," Shepard said. "We were talking and they were telling me how they would use me."
