In fact, I'm sure you haven't. But these guys know their stuff. It would be hard to get one of them, but the results would be completely worthwhile. So here we go:

Chuck Noll

This man built the Steel Curtain in Pittsburgh, need I say any more really? He was a defensive mastermind whose 1968 Colts defense set a record for fewest points allowed. He also used defense to win 4 Super Bowls as a head coach. And he is still alive, making him a particularly attractive option on this list.

Paul "Bear' Bryant

Sure, he was a college coach, but every team he touched turned to gold. And more often than not, they had stifling defenses. In 1961 his Alabama team held all opponents to a combined total of 25 points. They pitched five straight shut-outs. He was a hard-nosed, take-no-prisoners kind of coach. Bringing him back from the dead would be well worth Jeff Lurie's soul (which will undoubtedly need to be sold to the devil to make this happen).

Gianluigi Buffon

Ok, maybe he plays the wrong "football", but he could be go down as the greatest goalkeeper of all time once he retires! There is absolutely no question this man knows how to stop his opponents from scoring. He anchored a World Cup team just 4.5 years ago that won with stifling defense. It's true that he is still actively playing, but a good enough contract offer might lure him away. Why not try, Eagles?

King Leonidas I

He led the famous defensive battle at Thermopylae in 480 BC. Technically he lost, but the odds were so stacked against him that what success he did have in that battle has to be considered one of the greatest defensive stands of all time. Just think what he could do given the proper resources, FA signings and draft choices.

Georgy Zhukov (pictured), Kliment Voroshilov, Leonid Govorov

These were the three primary Soviet commanders tasked with defending Leningrad from the Axis forces during World War II. The Siege of Leningrad by the Axis lasted 872 days and was one of the costliest sieges in history in terms of both loss of life and destruction. But Leningrad never fell. You can't argue against that kind of defense.

Qin Shi Huang

He was the first Chinese emperor to order the building of a great wall. The wall as we know it today was built primarily during the Ming Dynasty, but without Qin's forethought and innovative (at the time) thinking, The Great Wall of China might never have been.

Brigadier General Daniel Morgan

He led the American forces at the Battle of Cowpens. It was a decisive American victory and an excellently executed counterattack. His plan was simple, but original and innovative. The British were tricked into believing themselves more successful early on than they truly were, thus exhausting themselves before engaging even more American forces. Considering we have several weak spots on our defense, perhaps someone with innovative strategies is best suited to us. Add to the fact that he is an American patriot and this is my personal choice. Make it happen! Daniel Morgan for DC of the Philadelphia Eagles!

What do you think? Are any of these more or less likely than say, Tony Dungy or Jon Gruden?
