"I just want to experience the whole USC tradition, and the program firsthand. I've only been to campus once or twice," the five-star receiver said.
Treggs visited USC last spring during one of the Trojans' practices, at a point when he expressed "a little bit of interest" in USC. But in the past year, he and a handful of players have formed the unofficial 'Cal Gang,' and helped to make California one of the top recruiting classes in the class of 2012. That was until defensive line Tosh Lupoi and wide receivers coach Eric Kiesau departed for Washington last week.
"My position coach actually left Cal, Coach Kiesau. Me and him had a great relationship," Treggs said. "He was one of the reasons I committed to Cal so when he left now I'm just exploring other options. I'm still pretty committed to Cal though."
The Bellflower (Calif.) St. John Bosco High player is the fifth-best wide receiver in the nation, according to Scout. And he knows he'd be joining a slew of top pass-catchers if he came to USC, along with a respected receivers coach in Ted Gilmore.
"They are on me pretty tough, telling me that they want me to come and they're going to a national championship next year. And I actually want to be a part of that. And they told me I can come in and compete," Treggs said.
"I know [USC] is a good academic school and has a huge alumni network and that's appealing."
Treggs has been in constant communication with USC running backs coach Kennedy Polamalu, who plans to show Treggs around Thursday.
"Coach Pola is telling me that he likes me as both a player and as a person. To pull out the red carpet for me and show me what USC has to offer."
Treggs plans to study either business or communication when he enters college.
"Pola said he would show me something about my major," he said.
Treggs plans to get to the campus at 3 p.m. Thursday for his official visit.
