Coaching can be a wonderful help. For example, think about how much this little girl in the picture is learning about baseball from the creepy guy in the trucker hat. Coaching can also be a detriment. Like if the coach of a Super Bowl team really isn't a great coach after all and kinda got lucky.

So who comes to mind when you think about the worst coach ever to roam the sidelines for a Super Bowl team? There are a number of options. The Super Bowl era started in 1966, when Vince Lombardi's green bay packers routed Hank Stram's Kansas City Chiefs 35-10. That is a limited amount of prospects to consider, compared to say, the World Series, but there are still some good candidates.

Just looking at career win-loss records provides some evidence. In fact, only three coaches with career records under .500 have ever led their teams to a Super Bowl. All lost the game.

- Forrest Gregg led the 1981 Cincinnati Bengals to the Super Bowl, which they lost to San Francisco. His career record was 75-85-1, a .469 winning percentage. In 11 years coaching the Bengals, Cleveland Browns and Green Bay Packers, he had only three winning seasons. However, he did have a Hall of Fame playing career with Green Bay.

- Sam Wyche also led the Bengals to a loss against San Francisco in the Super Bowl, in 1988. Wyche has the lowest winning percentage of any Super Bowl coach at .440. He coached 12 years for Cincinnati and Tampa Bay, and managed just three winning seasons, ending with a record of 84-107.

- Finally, Bill Callahan, recently fired from the University of Nebraska, led the 2002 Oakland Raiders into the Super Bowl, only to get trashed 48-21 by Tampa Bay. Callahan only got two seasons as the head man, and finished 15-17, for a .469 winning percentage.

Still, there are others that can at least be considered with the above trio. Current Carolina Panthers coach John Fox has twice won 11 games, but has also been 7-9 three times. Ray Malavasi coached only six seasons, but his record was less than impressive. After leading the Giants to the Super Bowl in 2000, Jim Fassel's phone hasn't been ringing with offers since he was fired.

But the truth is most coaches who have led their teams to the Super Bowl have excellent career records and are held in high regard, even if they went 0-4, like Bud Grant, Dan Reeves and Marv Levy each did. However, they do have one thing in common with each of the men listed above: none has a Super Bowl ring.
