He certainly is not in the upper echelon of the coaching ranks, but calling him a joke just shows your ignorance. The vast majority of coaches eventually fail as a head coach, there aren't many that have 10 years of success followed by a celebrated retirement. There are literally hundreds of NFL coaches with less years as a coach, less wins as a coach, a lower winning percentage, and less playoff appearances. There is an even higher percentage of college coaches that fared far worse during their tenure than Wannstedt.
The Dolphins won 41 games over 4 seasons (4 more wins than during the 4 precious years under Jimmy Johnson) before the 2004 disaster. Before that season, Rick Williams retired (after having nearly 4,000 yards of offense over the previous 2 seasons), Marino was hired then quit as VP of Football Operations, and their new VP traded away high draft picks for AJ Feeley, and traded away the team's reigning MVP in Ogunleye.
He was an average head coach at worst.
Sour grapes for some reason with a few goofs, same ones who want to give Duzz 8 years to see. Transparent as hell
