The cracks in the players' union leadership that started to form during the closing days of the lockout have exploded in recent days into a full-blown conflict. The National Basketball Players Association's eight-member executive committee released a statement Friday asking Oklahoma City Thunder guard and union president Derek Fisher to resign. Fisher has refused, saying the attack comes from the committee and executive director after Fisher requested a review of the union's finances by an outside firm, multiple reports suggest. Pistons player representative Ben Gordon, who took an active role in the labor negotiations, said he was aware of the power struggle but stopped short of taking a side.
