9. Jeff Fisher
One of the strangest entries on this list, Fisher was head coach of the Tennessee Titans for an incredible 17 seasons before five with the Rams. However, his overall lack of success stains his record as a head coach. He only posted six winning seasons despite over two decades of coaching in the NFL. That’s an incredible statistic.
His best moment was bringing the Titans to their first-ever Super Bowl appearance in 1999. Fisher plodded on for another 11 seasons in Nashville before agreeing to part ways. Meanwhile, his time with the Rams saw them post losing records every season. Fisher is famously disdainful of quarterbacks and arguably overstayed his welcome with both franchises.
