"That's all I've done in high school and AAU," Newton said, "pick-and-rolls, and ball screens."
"He's long, and he's going to be able to break guys down and make plays for himself and others," Neumann-Goretti coach Carl Arrigale said.
The 6-foot-2 Southwest Philadelphia native made his decision after a standout summer. The city's top high school player averaged more than 20 points in the AAU Super Showcase in Orlando and helped his team reach the semifinals two weekends ago.
Newton averaged 18.4 points in 29 games last season and led Neumann-Goretti to its fifth straight Catholic League title.
Despite not making a formal visit to Miami, Newton told his coaches he was ready to commit Tuesday night. After heeding their advice to sleep on it, Newton was comfortable enough with the decision to make it official Wednesday.
"They've been on him for a long time, so he's comfortable with the situation," Arrigale said of Miami. "He sounded great and really at ease and happy with it."
"I've known for a while now," Newton said. "I just waited things out and weighed my options."
According to Arrigale, Miami has recruited Newton for "well over a year," and Newton had talked about Miami as a possibility last year.
Newton, who plans to make a formal visit in September, was ready to end the recruiting process.
"I wanted to get it out of the way," Newton said. "I was tired of it with everyone asking where I was going and people calling.
"I can go into my senior year free and just play."
Arrigale noticed Newton getting more attention leading up to his decision.
"Some schools thought he would stay home, and when they realized he could go away, interest went up," he said. "Outside the area, I think [Miami] was coming the hardest, and they did a good job."
