The NCAA is not as powerful as you think. Remember this past summer when it appeared the whole Division I power conferences were going to have a major revamping? There was nothing the NCAA could do about that even though everyone knew it was probably not good for the sport.
The NCAA also has no control over broadcasting rights within the conference or even individual teams (see Notre Dame football). Years ago, they thought they did. The courts struck it down, and every conference (and in some cases individual teams) had the freedom to negotiate their own broadcast rights. The NCAA can only control the games they control -- the playoffs. Heck, they don't even get anything from the tons of money the BCS Bowls get. I read the NCAA gets a total of $400,000 for all 35 bowl games, and that is only payment for the NCAA to recognize and bless a bowl.
The NCAA does essentially three things -- 1) write the rules for the games, 2) set the eligibility rules and enforce them, and 3) administrate national playoffs.
They may do the above three things with a draconian hand, but beyond that, they essentially have no power.
Yep, and your point is...?
It's worse in the larger sports. Here is a perfect example. SUNYIT pulled out of the SUNYAC because with the exception of one team, they were very uncompetitive in that league in all sports. They joined the NEAC, a lesser competitive conference.
The SUNYIT men's basketball team was a bottom dweller in the SUNYAC. In their first year in the NEAC, they won the conference and went to the NCAA playoffs thanks to the AQ. If they were a bottom dweller in the SUNYAC, just think how many other teams in other conferences just as competitive as the SUNYAC that also did not make the playoffs while SUNYIT got in?
There has to be a cut off somewhere, otherwise everyone would create two-team conferences... The cutoff happens to be seven. The ECAC West has to live with it.
Again, they don't have that power or control, and quite frankly, I doubt any of the college presidents (who are the real ones behind the NCAA and its power) will ever want it that way.
Nobody is set adrift. You can still make it in as a Pool C bid. Sure, being an independant is tough, especially in the smaller sports, but nobody is being set adrift.
I'm okay with autobids. That's why they have at-large bids to fall back on for some teams.
