"I was excited to add another offer to my list, I was happy," said Brown, who posted a game-high 25 points in the title game loss.
"I have no favorites yet, I really am not looking at that yet," Brown said.
This past season, Brown was unable to visit Northwestern due to conflicting basketball schedules, but hopes to do so in the future. Brown's lead recruiter, Tavaras Hardy, has stayed in contact with his father.
The family has a strong relationship with NU's associate head coach.
"He's a good guy," Brown said of Hardy. "Nice, tells me what I need to work on. He's a nice, good guy."
Brown hopes to learn more about Northwestern, but feels highly about the school and its basketball program.
"(Northwestern has) a good school, good campus, and a nice basketball team," he said.
Brown is driven by a fiesty brotherly competition on the basketball court. His older brother, Shannon, is a six-year NBA veteran, currently playing with the Phoenix Suns.
"(Shannon) just gives me some motivation, some words to think about," Sterling said of his older brother.
The two compete in one-on-one basketball when Shannon, a former star at Michigan State, returns home to Maywood.
"He always wins," Sterling joked. "But he makes it easy on me."
