7. Dave Campo
How did Campo last three seasons as the Dallas Cowboys head coach? In three years, his team was 5-11 every season. This leaves him with the unpleasant accolades of being the only coach in franchise history to leave with an overall losing record and to never post a winning record. In short, this was a very dark time for Cowboys fans.
He got away with a weak first season because the roster was poor. But his second year saw the franchise sign better players without making progress on the field. Campo has a great reputation as a defensive coordinator but just wasn’t able to handle the top job.
