I certainly see what you are aiming for with the suggestion, however; the big issue with this in BB is that teams will every season promote and demote in and out of leagues, so, unlike the NBA, each season a team could find itself in a different group of 16 and I think the tracking of draft position and rank in the new Division would be a nightmare if not impossible to get 'fair'.
I can't wait to get my team and have a crack... no matter what the rules. I think if BB wants to implement a new aspect and it comes with a choice, then awesome, if I like the new aspect and I want in, then great, if not, I would just hum along merrily doing what i have already been doing.
I think too many non-supporters feel too strongly about the changes and updates that happen to this game for their true contribution to the game.
