The Las Vegas Review-Journal (Steve Carp) reports: For now, Las Vegas will have to be content with its lone tie to the NBA, as the host city for the annual Summer League. Commissioner David Stern said the league is not in a position to add members, and relocation is not an option because there is no NBA-quality arena in Las Vegas. “It’s more about the economy than the arena,” Stern said. “The idea of expansion, of building arenas, it’s waiting to see if the economy has bottomed out, what it’s going to do.”
