The three-star, 6-foot-7 forward made the call on his birthday, and will make the two-hour drive to campus for the season opener tonight.
"I feel good to join the family," Butts said. "I know Rutgers was the right choice because I like the campus and the coaches a lot. I could have a chance to play early."
Butts visited Rutgers in September, and said the experience with Jordan and assistant head coach David Cox had him almost ready to commit then.
"I fell in love with their campus, that was my favorite part," Butts said. "It's just a great place."
Butts played last year at Arlington (Va.) Bishop O'Connell alongside now Rutgers freshman Junior Etou. He got to know Jordan and Cox because of their ties to his AAU program DC Assault.
"He (Jordan) is a great coach." Butts said. "He's an NBA coach, and he was very good. He knows what it takes. … He said they need guys like me in their class because they're losing a lot. I'd get a chance to play right away because they're not going to have a lot at my position."
"Leroy is a versatile forward who really runs the court well," said Scout.com national basketball analyst Brian Snow. "He's a pretty good rebounded. He's developing on offense, but his motor and his athleticism is what separates him as a prospect."
