Of the roughly 100 or so (according to your first post) people that this issue affects, I have seen only a few who are so upset about it. I have no problem with it. If people take a look at NBA arenas, they will see that they of them are fairly similar in their size and seat distribution-
(http://en.wikipedia.org/wiki/List_of_National_Basketball_...).
I think there are some people who just want to complain about things, whether they are major or minor. I spend quite a bit of time on this site, my team is fairly competitive, and I try to participate in all facets of the game (except the draft). This change made me say, "hmmm, bummer. okay." And that was it. SO the arena has a cap on it. Fine. Those who tell you that it is ruining their "long-term" plans are misleading themselves. I also don't buy the timing complaint. 6 weeks is enough time to deal with any change. It might be a bumpy road for some ( although I don't see how since any team with 500+ courtside seats most likely has assets of at least 15 million dollars and more like 25 in these days of TL inflation ) but with the reduction of courtside seats and an increase in prices for both courtside and luxury box ticket prices, the majority of those 100 owners will roughly break even.
My responses to your questions:
1) soft cap
2) tomorrow.
3) the more freedom the builder has, the better.
Once I scored a basket that still makes me laugh.
