After back-to-back gold medals, the United States has repositioned itself as the perennial favorite for Olympic basketball. But a potential age limit might exclude several current Olympians, including LeBron James, from rejoining the team in 2016.

From ABC Chicago:

James said he wouldn't play anymore if the age limit was implemented, even if he was granted an exception, because he wouldn't want to play without his teammates. So there's still a chance the Americans could have the game's best player, who would be 31 in Rio, wearing red, white and blue for a fourth straight Olympics.

As for those teammates, Kobe Bryant has already said he is retiring from international play, while fellow 2008 and 2012 Olympians Carmelo Anthony, Chris Paul and Deron Williams have not yet committed to anything.

The team's head coach, Mike Krzyzewski, will be calling it a career for international play.
