KANSAS CITY, Mo. (AP) – Kansas got the best of ‘ol Roy and his Tar Heels once again. Behind the impassioned play of Travis Releford and Jeff Withey, the top-seeded Jayhawks shook themselves out of a first-half slumber and blitzed No. 8 seed North Carolina down the stretch for a 70-58 victory Sunday in the third round of the NCAA tournament. Withey had 16 points and 16 rebounds, and Releford finished with 22 points for the Jayhawks (31-5), who also knocked former coach Roy Williams’ team out of the NCAA tournament during their 2008 title run and again last season, when Kansas marched all the way to the Final Four. It’ll keep marching this year – at least to the Sweet 16 – thanks to a superb second half. P.J. Hairston scored 15 points and James Michael McAdoo finished with 11 for the Tar Heels (25-11).
