"I accepted an invitation to the U.S. Army Bowl," said Shittu. "It's definitely a dream come true."
"That was big because that was one I was waiting for," said Shittu. "Coach (Ed) Orgeron told me it was coming and then on Monday, Coach (Lane) Kiffin offered. I loved the school and the campus. USC is definitely going to be one of my final eight."
Also likely to make the cut is UCLA, where Shittu visited last Saturday, taking in a Bruins' spring practice.
"I loved it at UCLA," said Shittu. "The campus was nice and I think they're the next time in my final eight."
"Stanford and USC and probably UCLA are three I know will be in my final eight," said Shittu. "I'll figure out the other schools later."
Shittu said he'll likely take in a few more unofficial visits in the spring and will likely be at the Stanford Nike Camp next month.
A member of the Scout Top 50, Shittu said he's even surprised by the recruiting attention he's gotten.
"I've always know I could play, but I never knew to these levels," said Shittu.
Academically, he has a 3.8 and took the SAT earlier this spring.
As a junior, he had 75 tackles, 6.5 sacks, three forced fumbles and a fumble recovery.
