Drew Henson won't be on the Dallas Cowboys roster this season, and the team is apparently trying to trade the player who was considered the team's quarterback of the future when he signed three years ago. "I just didn't see enough," coach Bill Parcells said Wednesday. Parcells said Henson hadn't been waived, but the coach wouldn't elaborate when asked if the Cowboys were trying to trade the quarterback who started only one game for Dallas. "I'm really not at liberty to discuss the situation because I'm not privy to that information," Parcells said. "He's not going to be on our roster. That's all you need to know."
