Ohio State standout Jared Sullinger blames himself for the fifth-ranked Buckeyes' most recent loss.

"There were times in the Illinois game where I just kind of took a break on the defensive end instead of the offensive end and it cost us," Sullinger said, referring to a 79-74 setback on Tuesday. "Honestly, I was one of those people who played hard when they wanted to. I have to stop that."

Sullinger promises to recommit himself and make up for that lapse when the Buckeyes host No. 7 Indiana in a big rematch on Sunday.

"Coach (Thad) Matta always talks about how we have another gear, where we can take our games to the next level," Sullinger said. "I guess our coaches, they feel like I'm the best player so they feel like if I take my effort and leadership to a whole other level, everybody else is going to follow me."
