31. Jack Del Rio
Tom Coughlin did a solid job as the Jacksonville Jaguars’ first head coach. Finally, his tenure came to an end after the Jags fired him. They then brought in Del Rio in 2003. His record up until 2007 was good as he led Jacksonville to three winning seasons and two appearances in the postseason. However, he overstayed his welcome and the team went into an irreversible decline.

Unfortunately, he never led them to another winning season after this point as he continued for four more years. Del Rio’s inclusion definitely isn’t the worst on this list. However, he took the team as far as he could and arguably should have left earlier so that fresh ideas could be put in place. Sometimes, coaches can only do so much before a franchise needs to be refreshed.
