That's why there would have to be very well defined rules on the promotion and relegation of teams. I don't think it would be wise to promote a team after 1 year. I would say let it be similar to the realignment period. Every 2 or 3 years make the adjustments. That way you wouldn't have a "Cinderella" team getting the shaft and forcing them into a level everyone knows they couldn't compete in. True, it does raise a question of why even do it, but it's better we think of different ways that we could change to, than to wait and throw something together last minute.
