 The first practice for the U.S. Olympic basketball squad is set for tomorrow. Before they go to Paris at the end of the month, the basketball squad has a four-day training camp beginning before its exhibition opener against Canada on Wednesday. Players began arriving Thursday in Las Vegas. Stephen Curry was the first to check in. It'll be his first Olympics. The 12 players have all known each other for years. The U.S. team will seek a fifth consecutive gold medal. That's ABC's Chuck Sievertson reporting.
