Arizona’s Williams Will Enter NBA Draft: Arizona sophomore swingman Marcus Williams said he will leave school and enter the upcoming NBA draft. The 6-7 forward led the Wildcats in scoring, averaging 16.6 points per game, and was selected to the all-Pac 10 Conference team. Williams, 20, will hire an agent and hopes to be a first-round pick. “It’s always been a dream of mine to play in the NBA,” Williams said, “and I feel like I’m in a good position to take that next step.” [4/13/07]
