Publicly, at least, Duke coach Mike Krzyzewski is keeping expectations for Rivers from getting too high.

Rivers said recently that he needs to strengthen his skills and body and develop a defensive mindset, and Krzyzewski seems to agree.

"He's got to change," Krzyzewski said. "He's got to learn to become a complete player. For any freshman coming in, there's a huge difference in playing with older guys, more physical. It's a whole different thing."
