Coach Thad Matta says he doesn’t look closely at his Ohio State Buckeyes’ schedule. It’s a good thing. He might get an ulcer. The 10th-ranked Buckeyes face a daunting week when they travel to play No. 3 Michigan tonight ( 6, ESPN) and host top-ranked Indiana on Sunday. Even players who continually say they’re only worried about the next game are aware of the upcoming task. Ohio State’s leading scorer, Deshaun Thomas, welcomes the defensive challenges he’ll face. Point guard Aaron Craft said he likes where the Buckeyes are, tied for second in the Big Ten.
