What a royal joke. I have nothing personal against Luther (despite him being a choking dog), but he has no business on that team. They should have chosen a hot summer league player, like Westbrook or Bayless, who actually has a chance to be on a future Olympic team.
It's correct information... here is the official from USA Basketball http://usabasketball.com/news.php?news_page=2008mselteam
IMHO, given how "well" Luther played during the Utah series, they probably picked him to boost Deron Williams's confidence if anything.
