"In Beijing (in 2008) we had a team of experienced professionals; this team has younger professionals, outside of Odom and Billups," Krzyzewski said.
"We are trying to adapt (to different kinds of players) and it's good. I don't think the players should have to adapt to you as much as you should adapt to them."
Tyson Chandler is the team's only true center as well as its only 7-footer, but Krzyzewski said that situation was not intentional.
"We thought we would be bigger but the first day of training camp we lost (Brook) Lopez, (Amare) Stoudamire and (David) Lee and we could not bring other people in," he said. "There's more (chance of) error with the lack of size."
He added that he might use a zone defense extensively on Wednesday against Greece's tall frontline. "I could also use (Sofoklis) Schortsanitis," Krzyzewski joked, referring to Greece's 6-foot-10, 345-pound center.
His team must learn to adapt to international basketball rules, especially on traveling, a problem for many U.S. professionals, men and women, playing in Europe. In the game against Spain, the U.S. bench was furious at officials' numerous traveling calls.
"I understand that in the half court, you have to put the ball down before you move, but (calling a traveling violation) in the full court is something that's a little bit unusual," Krzyzewski said.
