Bol Bol and Louis King are joining Brandon Williams on his official visit to Oregon.

The two five-star recruits who have signed with the Ducks are looking to strengthen the highest-rated recruiting class in school history by convincing Williams to join them now that the spring signing period began Wednesday.

Bol and King are in Portland for the Nike Hoop Summit on Friday and will head to Eugene following the game.

“I’m just trying to get Brandon Williams to school,” King said.

The 7-foot-2 Bol promoted Oregon to top recruits Emmitt Williams and Shareef O’Neal before they signed with LSU and UCLA, respectively.

“I’m 0-for-2 right now, but I got this one,” Bol joked.

Bol is ranked as the No. 4 recruit in the country by 247Sports.com, and the 6-8 King is No. 17. Bol will play for Team USA in the Hoop Summit at Moda Center. King is out with a knee injury.

The 6-1 Williams is ranked as the No. 31 recruit by 247Sports following his senior season at Crespi Carmelite High School in Encino, Calif. The four-star point guard committed to Arizona before opening up his recruitment after the Wildcats came under NCAA scrutiny.

Bol and King are in a group message with Williams.

“We have a couple spots left on the roster so we have more recruits coming,” King said. “This is the best spot for (Williams).”

Oregon’s recruiting class, which also includes forward Miles Norris and guard Will Richardson, is ranked third in the nation by 247Sports, but could pass Kentucky for second if Williams signs with the Ducks.

“My birthday is on the 15th,” Norris said in a tweet to Williams. “I’m expecting a nice present.”

Williams recently visited Arizona State and also plans to visit Gonzaga while also still considering Arizona. The spring recruiting period runs through May 16, but Williams has indicated he could wait even longer before picking a school.

Williams is considered a true point guard while Richardson is a more of a combo guard. Oregon returns starting point guard Payton Pritchard, but he could play off the ball more often if Williams joins the roster. The Ducks also bring back sophomore Victor Bailey in the backcourt.
