9. Mike Nolan:
Nolan came from a strong football background thanks to his father. He also served as the defensive coordinator for several teams including the Giants, Redskins, Jets, Ravens, Broncos, Falcons, and Dolphins. He’s rarely struggled to find work in that regard, yet his head-coaching tenure in the NFL was an unmitigated disaster.

Nolan was hired as head coach of the legendary San Francisco 49ers in 2005. His first order of business was to select quarterback Alex Smith with the first overall pick of that year’s draft. Smith turned into a fine enough quarterback in his own right. But it was the fact that Nolan passed on future all-time great Aaron Rodgers that essentially sealed his fate before it began. He went 4-12, 7-9, and 5-11 in his first three seasons in the Bay Area. In 2008, he was fired before the halfway point of the season after posting a 2-5 record. Nolan is currently the linebackers coach for the New Orleans Saints.
