One of the reasons Rooks chose Cal was his overall comfort level in the school.
"It's where he was most comfortable," said Anthony Bolton, who coaches Rooks with his high school and Gamepoint AAU team. "Obviously with every decision there are pros and cons, but he was comfortable with the staff, the school, the program and the academics. Everything fit him as a person and a player."
Bolton credited the Cal coaching staff for doing a good job building a relationship with Rooks over the past month to the point where he was comfortable going to Berkeley.
"They did a very good job," he said. "Travis DeCuire came down to see us, and so did Gregg Gottlieb and John Montgomery. They did a great job recruiting him. Travis drove down to the Mission Prep tournament just to see us. They made a great effort of establishing a relationship with us."
"I like how hands on the coaching staff is and how they coach their bigs," said Rooks. "They know how to use their big men."
When Rooks arrives at California as a freshman, he won't have expectations for playing time, one way or the other.
"He has a long time between the end of his senior year to the beginning of his freshman year where he's going to put a lot of work in and we'll see where he's at; there are no expectations," Bolton said.
"He's not expecting to play and he's not expecting to sit. He's going to get to work and see where he's at when he gets there. If he plays then he'll be happy and if not he's understanding that he'll need to continue to work and get better until he's ready to go."
Rooks is joining a talented 2013 recruiting class at California, something that made his decision easier.
The Cal commit is already looking forward to getting on campus and making an impact.
"I see myself going out there and playing as hard as I can," Rooks said. "I'll rebound, help on offense and try to get people open.
