The younger Cochran has been to campus four or five times and knows offensive coordinator and offensive line coach Jim Michalczik from his multiple in-home visits.
Still, Aaron made his way to Berkeley for Junior Day on Saturday, hanging out with Concord (Calif.) De La Salle linebacker Michael Hutchings and Auburn (Calif.) Placer defensive tackle Eddie Vanderdoes.
Cochran was impressed with what Cal presented.
"I definitely know when coaches are just trying to sell me," said Cochran, after seeing the recruitment of defensive tackle Aziz Shittu and his brother up close. "They did a good job of just showing what their program is about."
Cochran also has a strong rapport with Michalczik, saying the veteran assistant is a "laid back guy.
"I feel like I can talk to him about anything," Cochran said. "I like Coach M."
And while the chance to play with his brother in college is intriguing to Cochran, it won't be the deciding factor.
"It's not a huge selling point. I'm focusing on finding the best fit for me," he said.
Cochran holds offers from Cal, Notre Dame, Colorado, Washington and Washington State. He is also hearing from Arizona State, Utah, Penn State and Michigan and believes offers could be coming soon.
Cochran said he plans to visit schools of interest unofficially this summer.
