Calathes, who grew up in Florida and played collegiately for the Florida Gators, was a second-round draft pick (45th overall) in 2009 whose rights were traded by Minnesota to the Dallas Mavericks. A relatively new rule instituted by FIBA prevented him from playing for the Mavericks' summer league team in July because he is under a contract with Panathinaikos for two more years, but he has a $500,000 buyout clause that can be exercised next summer if the Mavericks want to bring him to the NBA. He spent last season playing behind national team members Dimitrios Diamantidis and Vassilis Spanoulis on Panathinaikos, but his playing time figures to increase next season now that Spanoulis has switched teams -- leaving Panathinaikos to sign a three-year deal with archrival Olympiacos. "I think it all depends on how I do this year, how I play and how our team does -- and, of course, what the Mavericks want to do," Calathes said. "I like it over here, but it is still my dream to play in the NBA."
