"It's a dream come true," said Famer, who committed in October. "I always dreamed of getting a scholarship and going to college and I can't ask for anything else."
Farmer said he always imagined himself suiting up for Cal when playing video games as a young child.
"Cal has always been my dream school since I was like six years old. I always played games with them when I was little," said Farmer. "I like Marshawn Lynch, so I always used him."
The 6-1, 195-pound junior is a standout wide receiver and defensive back for his high school team and is being recruited as a safety. He has good size, speed and very good football instincts.
Farmer will be one of the top safeties in Southern California next year and said Cal's strong academics and location were big factors in his decision to commit.
"I like how it isn't too far from here but isn't too close," he said. "It's a great academic school as well so when they offered, it was a dream."
