That will come after the spring.
What he already knows, though, is one school that will be part of his final grouping.
"I'm definitely taking (an official visit) to Notre Dame. I know that," the 5-foot-11, 175-pound Treggs told IrishEyes.com. "They're definitely going to be in my top five."
The interest is mutual as Notre Dame assistant coach Mike Denbrock is slated to visit Treggs next week.
Treggs wasn't sure when then official visit would be, but he already knows he likes the campus. He was in South Bend, Ind., for last month's Blue-Gold game, and was highly impressed with Notre Dame's program.
He also had the opportunity to talk with Irish commit Tee Shepard, who plays three hours from Bellflower at Central High East in Fresno, and the two continue to speak.
"I hung out with him a little bit, and we talked about the whole atmosphere, the stadium and everything," Treggs said. "I loved it."
The game was the only thing Treggs enjoyed about the visit, or the Irish.
"I like them a lot," he said. "The football atmosphere over there is great. There's no other place like that in the country. I like that. I like the academics. I like the players there. I like the type of people they recruit."
Treggs is Scout.com's 12th-rated receiver in the 2012 class, and is coming off a junior season in which he caught 56 passes for 1,010 yards and 12 touchdowns. He was also a consistent performance, catching at least one touchdown in nine of St. John Bosco's 10 games, and registering more than 100 receiving yards six times.
The Braves run a spread offense, and Treggs believes a transition into the Notre Dame's offense could run smoothly.
"It's good because I won't have to think when I'm playing," Treggs said. "I could go out there and play because I'm so used to running the spread."
There are plenty of teams showing Treggs interest, and for the Irish to land him, it will have to pry him out of the Pac-12.
"Oregon is showing me a lot of love, (and) Cal, Oregon State, Washington and UCLA, Arizona, Arizona State and Notre Dame," Treggs said. "I'm still checking things out. I haven't cut my list down yet."
Treggs said he doesn't envision selecting a school until after the season.
"I'm going to do my trips before I make a final decision," he said. "It's going to be either the Pac-12 or Notre Dame."
