Though average NBA teams play their starters much more per week then we can in BB. Here's the top 5 in total minutes for the Lakers during 08-09 last year:
NAME..........gm/wk.. mn/wk..mn/gm
Kobe Bryant....3.4.....123.3....36.1
Pau Gasol .......3.4......125.0....37.0
Lamar Odom....3.3......96.5......29.7
Derek Fisher....3.4.....101.7....29.8
Trevor Ariza....3.4......83.3.....24.4

I'm not saying this is poor game design, but it is different from the reality of most professional team.
And like the Lakers, if you play your key players between 29.8 and 36.1 minutes in every league game and in no other competitive games, it'll come out just about perfectly.
This of course being the key part of the sentence, since the Lakers don't have any other competitive games to play, but the majority of BB users do.
Another, more realistic, way of putting the phrase would be that any normal team (the Lakers in this example) can play their best players in EVERY game, while BB owners can only play their best players in 2 games out of 3. And this is why you don't see the Lakers throwing games, and on the other hand you DO see this wide-spread phenomenon amongst BB owners who play in competitive leagues.
The whole discussion about whether this is good/bad/horrible/terrific/etc. etc. management is simply a moot point, because just observing the reality of the BB world and seeing that this phenomenon is taking place in EVERY major league in the BB world tells you that either a)the most successful users are idiots (not very likely) or b)all users are forced into this kind of "behaviour" by a set of rules which are incompatible with each other (game-shape/minutes/salary).
I'm guessing that if the Lakers purposely put their 8-12th best players on the field and lost by 80 points once every week, the commissioner would look into the matter and do something about it. I don't know if the BBs are looking into the matter and are considering whether to do something about it, but ignoring the issue or even justifying this set of rules with comments like the one above is frankly discouraging to all users who would like to see BB improve.
