Why the Popularity in Former Phillies as Coaches?

Whenever I catch a news clip that a former Phillie has joined the ranks of coach, I do my best to whip up a post right here to let you, my die-hard fan(s) know about it. It's a blog, it's free, and it's moderately enjoyable for me to do so, so I do it. Thanks for following along.

At any rate, I have a real hankering to understand what the fascination is with former Phillies blossoming into coaches around the league. I did a rough scan over every MLB team's coaching roster and came across the following coaches who at one time or another played for the Phillies:

John Russell, Pirates
Lee Elia, Mariners
Nick Leyva, Brewers (formerly)
Dale Sveum, Brewers
Mike Maddux, Brewers
Rick Schu, Diamondbacks
Larry Bowa, Dodgers (as of today actually)
Terry Francona, Red Sox
Juan Samuel, Orioles
Ron Roenicke, Angels
Roger McDowell, Braves
Ivan DeJesus, Cubs
Mariano Duncan, Dodgers
Norm Charlton, Mariners
Tom Nieto, Mets
Pat Corrales, Nationals
Darrel Akerfelds, Padres
Milt Thompson, Phillies
Billy Hatcher, Reds
Andy Van Slyke, Tigers

That's quite a list. 20 coaches. That seems like a very high proportion, considering the average team had roughly 6 coaches listed. That's about 120 coaches in the league, meaning that 1 in every 6 coaches was a former Phillie player or coach. Quite enthralling data there.

So here's the question... why are so many former Phillies now coaches, despite the team's minimal success over the past 3 decades or so?

Some theories:

1. Flipping through some of their playing records on Baseball-Reference.com, I noticed that most of these guys played for a good 5 teams or more. AKA- journeymen. So, not only were they former Philles, but they were former "everythings".

2. Perhaps playing on the infamous Veterans Stadium turf taught these gents the nitty gritty of how to play baseball better. Note that this theory is quickly rebuked after considering the Phils' dismal collective record over the past 30-odd years.

3. Maybe these teams want coaches with plenty of experience in dealing with adversity. As mentioned, most of these guys played on the Vet's turf. They also dealt with futile teams. And hostile fans. And weather that went from ice cold in April to 100 degrees with 99% humidity in the summer. Talk about survivors, these guys have seen it all.

4. Or perhaps there's a mysterious missing link. Was/is there a great mentor that these guys learned from while in Philly? Was there a secret network that these guys had to help them get hooked up with coaching jobs? Or something else altogether?

5. Lastly, the most likely cause: the Phanatic. I don't know what his effect could possibly be, but he's the only constant in the past 30+ years. Can we get a scientific link to his powers of getting former Phils to become coaches all over the league?

You be the judge.
