The Dolphins believe they have put head coach Tony Sparano in a tough spot by starting the season 0-3. "We're putting him in a tough situation," linebacker Karlos Dansby said. "We've got to play better. Right now his job is on the line, and we've got to do a better job of defending it for him. We're the only ones who can." One day after a 17-16 loss Sunday at Cleveland, Sparano talked with reporters for 20 minutes but addressed his job insecurity only briefly. "I don't know anything about that," he said. "I'm getting ready for the San Diego Chargers." Including last season, Miami has dropped six games in a row.
