This may not be a preview to 2014, when LeBron James, Dwyane Wade and Chris Bosh hold their opt-out clauses, but the Heat are in the midst of having the opportunity to experience some of the more chilling aspects of the NBA's new collective-bargaining agreement. Last Sunday, it was Rudy Gay in a Toronto Raptors uniform. Wednesday, it was James Harden as a member of the Houston Rockets. And Thursday, when the Heat visit the Oklahoma City Thunder for the first time since last season's NBA Finals, it will be with Kevin Martin cast in the role of Harden. New faces in different places, with the repositioning based almost entirely on money. "It's the economics of our business," Heat forward Shane Battier said. For Battier, that meant seeing his previous team, the Memphis Grizzlies, ripped apart by the Gay trade, amid concerns of an impending luxury-tax hit, just as the Grizzlies appeared to be hitting their stride.
