26. Steve Spagnuolo
Spagnuolo masterminded the Giants’ defense in their shock Super Bowl XLII win over the Patriots that ended New England’s bid for the elusive perfect season. The St. Louis Rams swiftly identified the coordinator as their next head coach. Excitement surrounded his arrival but it swiftly turned to dismay after he led the Rams to the worst season in their history. That’s right, they went 1-15 but he still managed to hang onto his job.

The following season he improved the Rams’ fortunes to 7-9. The Rams were patient and pragmatic. They expected Spagnuolo to improve them further in year three. However, they regressed yet again as the ailing team finished with just two wins all year. Enough was enough because he had ground down their team into a disorganized mess.
