The NFL still wants the players to get out of the courts and come back to the bargaining table. Reiterating that mantra, lawyers for the league issued written arguments Thursday that a recent legal response by players does not dispel "serious doubts" previously expressed by an appeals court about a federal judge's order that the lockout end immediately. Repeatedly during this dragged-out, employer-employee dispute over the future of this lucrative, ever-popular professional sport, the NFL has insisted the only path to a new agreement is through face-to-face talks.
