1, attendance - best teams attendance go down..
except top division teams now find that they can charge more, and so top teams earn the same ON AVERAGE although the distribution is compressed, this is in an attempt to keep the gap between divisions at a appreciable, but not insurmountable level.
2, best teams will not draft good player never + they need good players to be best - in this way they haven´t pupil never..
I think something is lost in translation here, but I think you are saying that its hard for the best teams to stay at the top. I think this would be a feature of any league, its the "parity" that all the best sports leagues aim for, keeps the game exciting for all the teams and fans. We don't want a league like the Premier league in English football.
3, only domestic players are usable. foreign players are qualmish because merchandise advantage of domestic player is too big, and proclamation of top BB player merchandise advantage is only proclamation ....
This is an overexageration of this effect, yes they are better but not so prohibitively better that you shouldn't consider using a national player if he is good enough. It does put a premium on domestic players, and a premium on training players for the NT. This was the point of this design change.
are you saying you see no pop in merchandising for good statistics (league leader in points/rebounds/assists etc, and a smaller bump in other stats?) or you assume because you are the best team that you have the best players? As stated explicitly in the news we understand the best stats are often put up by the not best teams, and yes this helps them get a little more income and compress the distribution.
lets be honest about this debate, top teams complain when we make the game more competitive, lower teams complain when we reward the top teams, complaining it makes the game less competitive. Really what we are striving for is a balance between those two extremes where the game both rewards success, while remaining competitive at all levels such that anybody who works hard enough at it can reach the top. In other words the American dream all wrapped up into a neat little .com package ;) (forgive me i'm kidding in that last sentence).
