Tar Heels center Tyler Zeller is more aggressively battling for position, coach Roy Williams said.

“He’s going to the boards more; it’s pretty simple,’’ Williams said. “Early in the year, we’d have to yell at him to get to the boards, but I think he’s establishing a spot in there, he’s trying to get to the offensive boards. He got two offensive boards for baskets in the first half just by getting to the boards and finding an open spot. We need that.”

Indeed, Zeller has now pulled down 116 rebounds in his past 10 games, recording double-digit boards in nine of them.

In UNC’s first 10 games, he’d managed 10 or more rebounds only twice.

And entering this season, he had posted 10 or more rebounds only seven times.
