King, who was given his release from Duke earlier this month, will visit Villanova on Friday, and intends to take in Gonzaga and Southern Cal once he returns home to Huntington Beach, Calif., after completing his second freshman semester at Duke later this month.
"This is my last shot, so I don't want to mess it up," King, a 6-foot-6 forward, said. "I want to make sure it's the right fit and that I make the right decision. It's about bonding with the coach, the players, the academics and finding a place that will put me in the best position to play at the next level, whether that's in the NBA or overseas."
King, a McDonald's All-American, considered both Villanova and Gonzaga coming out of high school.
He played in all 34 games at Duke this season, averaging 5.9 points and 2.0 rebounds per game. He scored a career-high 27 against Eastern Kentucky.
"I love the school, the people here, but it wasn't a right fit," King said. "I gave it one year to see what happens, but it's time for something different."
