Bryce Treggs emerged from a group of five freshman wide receivers to earn a starting job 10 days before Cal's opener.
Coach Jeff Tedford released his first fall depth chart Wednesday, showing Treggs and punter Cole Leininger are the two first-year players in starting roles.
The Bears open at renovated Memorial Stadium on Sept. 1 against Nevada.
Treggs is the son of ex-Cal receiver Brian Treggs. Fellow freshman Chris Harper has climbed to second-string status, and Tedford said Darius Powe also "will play a major role" at wideout. Also, Cedric Dozier requested a move to defense and will play cornerback. He and Kenny Lawler are scheduled to redshirt this season.
"We knew going in a few of the freshmen (receivers) were going to have to contribute," Tedford. "(Treggs has) just gotten more comfortable day in and day out."
Austin Hinder secured the No. 3 quarterback spot behind starter Zach Maynard and Allan Bridgford, but Tedford said touted freshman Zach Kline of Danville will be part of the traveling squad.
Also, linebacker Khairi Fortt, a junior transfer from Penn State, continues to rehab after knee surgery he had last spring before arriving at Berkeley.
"It's all the logistics of the day," coach Mike MacIntyre said. "The classes and transportation for them, coming and going."
The team hits the practice field at 8:30 a.m. on SJSU's South Campus, about a mile away from the main campus. Practice ends around 11 a.m., and the players shower and scurry to noon classes.
It's a challenge not all teams have to deal with right away. Stanford, the team the Spartans open against Aug. 31, doesn't begin classes until Sept. 24. That's the same start date for UC Davis, which SJSU hosts Sept. 8.
"It's hard to organize your time," said senior defensive end Travis Johnson, who has earned Academic All-WAC honors the past three years.
Infielder-outfielder Bryson Brigman of San Jose was named to Team USA for the IBAF 18U/AAA World Championships on Aug. 30-Sept. 8 in Seoul, South Korea. The U.S. will also play exhibition games against Chinese Taiper on Aug. 25-27 in Taichung, Taiwan.
