Marvin Williams will not enter NBA draft

North Carolina's All-American signee Marvin Williams has decided against entering the NBA draft and will enroll at North Carolina this summer ...

"He's happy with [the decision]," his father, Marvin Williams Sr., told the Bremerton Sun-Link. "I really think it's a good decision for him. ... He needs to go to college and have some fun. Being coached by Roy Williams won't hurt him at all."

Roy Williams will be in Bremerton on Monday to "finalize all the details on summer school, which Marvin Jr. will attend starting June 16," according to the newspaper.
