NFL players whistle Goldman in labor dispute

"It's hard to find that Goldman Sachs would ask any of its clients to do a deal without full transparency," said George Atallah, an assistant executive director of the players' union and a former senior analyst and trader at Goldman.

"I've worked for Goldman and know what it believes," he said. "So it's doubly disappointing to me that they are so respected but apparently won't advise their clients to observe the most basic tenet of business."
