As expected, Arizona sophomore Marcus Williams announced Thursday that he will leave college to become eligible for the NBA draft.

Williams considered the NBA last year but decided it was best for him to stay for another season in Tucson. This year, the 20-year-old said he will hire an agent and will not return.

"I think I'm ready," Williams said. "It's going to give me a lot of opportunities to give back to my community. I felt like it was time. It was a hard decision, but the coaching staff has been great. I've had a lot of support from them."
