Ohio State's William Buford (44) drives against Indiana's Will Sheehey during the first half of an NCAA college basketball game Sunday, Jan. 15, 2012, in Columbus, Ohio.

COLUMBUS, Ohio — Lenzelle Smith Jr. more than doubled his career high with 28 on Sunday to lead No. 5 Ohio State to a surprisingly easy 80-63 victory over seventh-ranked Indiana.

Jared Sullinger added 16 points, William Buford scored 12 and Deshaun Thomas had 11 for the Buckeyes (16-3, 4-2 Big Ten), who were coming off a loss at Illinois on Tuesday night. Several players questioned their teammates' commitment and effort after that game.

There was no doubt about either on Sunday as Ohio State took command early and was never threatened.

Cody Zeller had 16 points, Christian Watford 13 and Jordan Hulls 11 for the Hoosiers (15-3, 3-3), who had lost at home to unranked Minnesota on Wednesday night.
