MILWAUKEE (AP) — Buzz Williams isn’t bragging when he says he doesn’t sleep very much these days. While some coaches seem to consider their workaholic ways to be a badge of honor, Williams isn’t pulling all-nighters at Marquette to prove a point about his dedication. Williams says he has been working with a doctor at the Mayo Clinic since last year and his ability to sleep had been improving until recently. Going into the Golden Eagles’ matchup with North Carolina in the round of 16 on Friday night, Williams’ restless ways have returned. But Williams doesn’t think anybody should pay any attention to his sleep problems going into what could be considered Marquette’s biggest game since its 2003 Final Four run.
