4. Dave Campo
At least Campo was consistent as that’s the only positive thing to say about his tenure as head coach of the Dallas Cowboys. His teams went 5-11 for three consecutive seasons from 2000-02. It’s remarkable really that he managed to achieve this. As a result, he is the only Cowboys head coach in history to depart with a losing record. Even worse, he was the first Dallas coach never to have a winning season.

He began coaching in 1971 but has only ever been a head coach once. This includes his college career. Initially, he faced challenges when Troy Aikman retired. But Campo simply wasn’t up to the job (via Dallas News). That’s not a slight because many coordinators and college coaches struggle to step up. This was a miserable period for fans of ‘America’s Team’ because they went nowhere.
