INDIANAPOLIS (AP) — A year after the NCAA Tournament was canceled, the madness returned with an opening weekend full of upsets. No. 1 seed Illinois is gone. So is second-seeded Ohio State. High seeds Texas and Virginia also are out, replaced by upstarts and mid-major noisemakers. And then there's Sister Jean, the 101-year-old nun who serves as team chaplain for Chicago Loyola. So good to have her back. AP Basketball Writer John Marshall says it was a wild opening ride to be sure and the tournament is all but guaranteed to have a few more unexpected twists and turns.
