There really isn't a "main skill" in BB.
I don't think the answer is to speed up the "end of the game." Players will eventually reach their peaks and decline, it is only seaosn 6, give it 4 more and you will see what they had been reaching for this whole time.
It would also be more realistic for players to start slowly declining when they hit 28-29. How many 32/33 yr olds do you see who are still as good as when they were 27/28?
Kevin Garnett - His minutes per game dropped last season after being pretty consistent through his career... And his average rpg and apg have been slowly dropping the last 3 seasonsRay Allen - His PPG dropped to 17 last season after being pretty consistent over his career at 23-25. You have an argument here.Jason Kidd - His PPG have dropped steadily since his career high of 18.7 in 2002-2003. Still, another good argument.I don't really know basketball that well, so you may be right.
