Johnathan Williams has withdrawn from the NBA Draft and will return for his senior season at Gonzaga, The Spokesman-Review has learned. Williams declared for the draft last month but didn’t hire an agent, retaining the option of returning to GU. Wednesday was the deadline for underclassmen to pull out of the draft. Williams took his decision down to the wire because he had workouts with Toronto on Monday and Denver on Tuesday. Williams will be Gonzaga’s top returning scorer (10.2 points) and shot-blocker (36). He was the team’s top rebounder (6.4). He averaged 10.6 points and 7.8 rebounds in WCC games and earned first-team honors. The 6-foot-9 forward stabilizes a frontcourt that lost 7-footers Przemek Karnowski (graduation), Zach Collins (NBA Draft) and Ryan Edwards, who elected not to play his senior season. Karnowski won the Kareem Abdul-Jabbar Award given to the nation’s top center. Collins is projected as a lottery pick.
