"It was the chemistry," Riley's mother Colette Anderson said. "We built a real good chemistry with the coaches. We thought that he could really get developed there. That's what Georgetown is known for, developing big men."
Also among the deciding factors was the relationship that Riley built with Georgetown assistant coach Kenya Hunter.
"I guess basically he was always consistent," she said. "He was always around. He was always there. He made it a point to always make contact and come to all of his games. He just basically kept in contact on a regular basis and never fell off."
Riley is currently rated as a five star prospect on Scout.com and is ranked No. 5 on Scout.com's center list.
