The Philadelphia Daily News (Phil Jasner) reports: “Because the Sixers did not make qualifying offers, forwards Shavlik Randolph, Louis Amundson and Herbert Hill have become unrestricted free agents, joining guard Kevin Ollie. Backup center Calvin Booth exercised his player option to return for about $1.1 million . . . Published reports indicate that the Sixers have invited former Saint Joseph’s University shooter Pat Carroll and Arizona guard Jawaan McClellan to join their summer league team in Las Vegas. The Sixers will open a rookie camp out there on Sunday . . . As expected, Samuel Dalembert was named to Canada’s national team that will compete in an Olympic qualifying tournament in Greece, July 14-20.”
