The Dolphins are winless this season at 0-6 and they have the NFL's longest losing streak at nine games, stretching back to last season. Miami coach Tony Sparano has been on the hot seat for a majority of the season and his status remains in question after the team blew a 15-0 lead with three minutes left against the Broncos on Sunday. "Of course he's the head coach and he's going to take a lot of heat," receiver Brandon Marshall said. "But trust me, it's not him. Not just him. It's all of us." The Dolphins lost for the 12th time in their past 13 home games. "I'm just discouraged for the players in the locker room," Sparano said. "They work really hard, and we don't have anything to show for it right now."
