Indiana's Cody Zeller turned down one chance to play in the NBA. He couldn't say no twice.

The 213-cm sophomore center who returned to school last fall for one more shot at a national championship announced Wednesday he is leaving college early to enter the NBA draft. The reason was simple.

"The leaders that I came in looking up to and copying their work ethic were Vic, Christian (Watford), Jordan (Hulls), Derek (Elston), a lot of those older guys that are leaving now," Zeller said explaining the difference between last year's decision and this year's. "IU will have a great year next year, but the guys I was closest to are graduating."

The decision was first announced on the website of his family's business shortly before the news conference at Assembly Hall.
