DETROIT — North Carolina coach Roy Williams says he doesn't have a specific timetable when juniors Ty Lawson and Wayne Ellington will decide if they will go to the NBA.

Williams said this morning that he hasn't spoken to the Tar Heels stars about their decision. Both players entered their names in the 2008 draft but returned to school.

Soon after the team's 2005 title four underclassmen opted for the NBA — Rashad McCants, Sean May, Raymond Felton and Marvin Williams — decisions the coach expected for the most part.

Williams has an idea what Lawson and Ellington will do, but "not with the conviction that I had last time."

The Heels were preparing for a championship celebration Tuesday afternoon at the Smith Center after beating Michigan State for the program's fifth national championship.
