that's a very good post. Great point made on the success of the wealthier community schools. Really more fodder for the argument that there is very little, if anything, separating the likes of Brentwood, Germantown (whom I lost to while at MBA), Riverdale, etc., and MBA/BA/MUS, etc.
as for the small privates, they are all very different, and the perceived advantages people cite aren't as great as people think. I know because my mom spent the first half of her teaching career in metro nashville, and the second half in a small private w/ no financial aid and no real emphasis on sports. Those schools have a very tough road to hoe. Given the glut of private schools in Nashville (I've lived all over the country and can't imagine there's a city with more private schools per capita), they have to devote a ton of energy to recruiting students--not athletes--just to keep the school in business. Some schools have recognized the power of sports as a recruiting tool (Ezell, CPA, etc.) and have hired well-known successful coaches. That's an area in which they have a distinct advantage over comparably sized publics. Where they are at a disadvantage is in the competition they face all over a town, like Nashville, for students. Not just with other privates but with publics as well. There are a number of schools that have to devote a tremendous amount of money and energy to marketing and advertising. A rural public has a captive audience one way or the other. I have witnessed this first-hand at my mothers' school.
The problem is, as you can glean from this board and any simple conversation, is that the minute one of these public schools loses to a small private, the knee-jerk reaction is "they're cheating." My mom's school went for years with exactly 22 players on the football team. Routinely lost 55-0. No one was feeling sorry for them then. But once they start winning, it's all about "recruiting, cheating, unfair advantages, etc."
