Eight of the NFL's last 12 Super Bowl winners have been coached by that group, and if you add Tampa Bay's Jon Gruden, who is just four wins shy of 100, the number of Super Bowl winners is nine.
Only Reid and Fisher have failed to win it all among that group, and since Fisher is sitting with the NFL's only unbeaten team at the moment, it's clearly better to be the head coach of the Titans right now than it is the 4-3 Eagles.
Of course, when someone joins a fraternity like this one, it's always fun to compare how the coaching brothers have fared against one another. In Reid's case, the answer is not good.
Reid's career record against the active members of the century club and member-in-waiting Gruden is 10-21. That .323 winning percentage is the worst of the eight coaches. Gruden, at 12-23, is the only coach who is even close to Reid.
It's not the worst thing in the world to be at the bottom of a list like this, but the difference between being a good coach and a great one probably depends on how you do against the best coaches in the biggest games.
Five years ago, it seemed as if Reid was going to be one of the best in the business at winning against the best in the business.
His ability to beat Tampa Bay twice in the playoffs was the reason Dungy ended up in Indianapolis. And Reid's first two trips to Seattle to face his mentor Holmgren both resulted in victories. Reid was 6-3 after his first nine meetings against the century club.
Since then, he is 4-18, with all four wins coming against Coughlin's Giants.
The trend started to turn the other way after the Eagles' NFC championship loss to Gruden's Buccaneers in 2003. Reid does not have a winning record against any other member of the elite club he just joined.
He is 0-1 against Shanahan, 0-3 against Belichick, 0-2 against Fisher, 4-6 against Coughlin, 1-4 against Gruden, 3-3 against Dungy and 2-2 against Holmgren.
