Jared Sullinger questioned the effort and togetherness of the Buckeyes after a 79-74 loss at Illinois.
"We need more guys to put their foot down and say enough is enough. We have to come together as a basketball team," Sullinger said. "We've got to like each other on the basketball court."
Ohio State is 15-3, with thirteen regular-season games remaining before the NCAA tournament.
"We have to come together," Sullinger said. "We've got too many things going on, I think, inside everybody's head. If we just listen to one voice ..."
Sullinger said he will become a more prominent voice in the locker room.
"I have to take my leadership and my effort to a whole 'nother level, and I guess this is the starting point," he said.
