The NFL and legendary head coaches have a strange relationship with one another.
The coaches could, certainly, return to the sidelines and guide a team to victory.
With no shortage of coaches on the hot seat in 2011, don't be surprised if one of these coaches ends up with a team next offseason.
Here are the top five NFL head coaches without coaching jobs, currently.
We've elected to disqualify a few coaches from this list due to circumstances surrounding their situations.
Marty Schottenheimer just joined up in the UFL, and he seems happier in the lower-key environment, so we'll keep him out of NFL consideration for now.
I don't see any way that Tony Dungy actually comes back to the NFL, so he won't be making a (well-deserved) appearance on this list.
Lastly, Bill Parcells is retired for real this time, and his career will live on in legend, not uncertainty.
One of this offseason's coaching carousel casualties, Jeff Fisher can still be a very good coach.
Fisher was been the longest-tenured current head coach for a time, showing that he can be a stable presence at the top.
The veteran coach also knows how to win, having compiled an overall record of 136-110.
The former Titan coach was just a yard away from winning the Super Bowl and he deserves another shot at the helm for an NFL team.
Billick is doing good work as an NFL TV personality, but with his football acumen and résumé, he should be back on the sidelines at some point.
The former Raven coach has a Super Bowl title, and knows how to inspire a group of players to be great.
Not only can he put a formidable defense on the field, but Billick also knows the ins and outs of offensive strategy.
The coach-turned-analyst was the offensive coordinator for the high-powered 1998 Minnesota Vikings, and deserves another shot to coach somewhere.
Jon Gruden falls a bit on the list because of his potential to blow up and let his ego cloud his judgement, but it's still Jon Gruden.
The former Buccaneer coach is a good, if unspectacular, 95-81 coach overall.
The TV analyst has a Super Bowl ring, which gives him true legitimacy as a head coach, and warrants him another shot in the NFL.
Gruden can come in and win, and in a what-have-you-done-for-me-lately league, this coach would succeed.
If Bill Cowher isn't No. 1, then someone very good must be first—such person is very good, but Cowher is not far off.
The former Steeler coach brings swagger and entitlement with him—any team he coaches would benefit from his coaching style.
Cowher has a Super Bowl ring, having won Super Bowl XL with Ben Roethlisberger and Co.
The confident coach would bring a winning mindset wherever he goes, and should warrant a look from any coach-needy NFL team.
This should inspire a lot of debate, but I believe Mike Holmgren is the best head coach who isn't a head coach right now.
He's a fantastic personnel guy and is well-liked by his players with a Super Bowl ring to boot.
Holmgren hasn't ruled out a return to the sidelines, but my guess is that he'll stay put with the Browns rebuilding effort for now.
