Next time you have a thought, just let it go.
For years, Maryville and Alcoa have had the opportunities to play up (yes, even in DI), but they haven't. Teams tend to play where they are classified...that would seem the normal course of action.
You also obviously don't understand that BA, EHS, BGA playing up isn't even in the same realm of decision making that would go into the administration at Webb moving up; drastically different schools in different areas with a wide variety of motivations behind their respective choices. BA and EHS are "sports" schools and BGA, by virtue of location, history, etc, has to lump themselves with those schools to compete in the private school market. Webb is much closer in the type of institution they are with DA, FRA, DCA, etc than teams in AA.
The previous set up of three classes in DII would remedy your problem, but as everyone involved in DII the past decade or so has seen, this method dilutes the division...but yea, you really are making zero valid points...so stop it. Enrollment in private schools plays a far less significant role in the talent of the athletic department than it does in DI. Why do you think there's a divisional split even with the multiplier?
