Here is a piece on Team USA and their desire to communicate more on the floor. From NBA.com:
"In the last two ball games, you knew you were going to win and you wanted to really fast forward into the medal round," head coach Mike Krzyzewski said after practice. "And what happens is you stop talking to one another on the court. And then you're not as animated. It's still a game of being connected, and you're connected primarily when you're talking to one another."
Communication on defense is always critical. But it takes on extra importance in international play, where the best teams run offenses with five players and the ball constantly in motion. A defense that does not talk will quickly be a defense that is lost.
"These teams are well-coached and they run all their sets all the way through," Kevin Durant said. "They have a lot of shooters that stretch the floor, so if you don't talk, you can get burned."
Defensive communication goes well beyond calling out screens. All five players must be talking and working together, so that the roll man is picked up quickly and the shooters aren't left alone. Rotations must be quick, and being a step slow will cost you two or three points.
Of course, the importance of communication is not limited to the defensive end of the floor. The U.S. offense has been stagnant at times, in part because they weren't talking as they brought the ball up the floor.
"We've been coming down, just dribbling the ball, and waiting to call a set instead of running some motion," Krzyzewski said, noting that early offense was another point of emphasis on Saturday.
Many of these American players aren't used to being vocal though. Along with a lack of international and big-game experience, that's one of the challenges of bringing a young team to the World Championship.
"It's different roles and situations that you're put in when you play USA Basketball," Tyson Chandler said. "So we've got to get guys out of their comfort zone."
"I know for myself, I was a little nervous when I first got here to talk it up," Durant admitted. "But as time goes on, these guys make it easier."
Krzyzewski puts a positive spin on the lack of communication, saying that it's also a result of players focused on doing the right thing individually.
"It's not meant like 'I don't want to talk,'" the coach said. "It's like 'I am talking, and I'm talking to myself. Here's what I'm supposed to be doing.' And we need to get them outside of themselves. And they will do that. They'll be a very enthusiastic, hungry group when we play Angola." (Who they beat by 56 points)
