c'mon man....are you really ignorant of the reasons for that?
the CBA's have changed dramatically over the years:

1999 was a sea change year.
Bob Whitsitt was hired as the GM when there were no maximum salaries and no salary caps. Paul Allen was willing to spend then even more than Steve Ballmer is willing to spend now (
with the same results apparently). It doesn't show on that chart but the Apron and Hard Cap provisions showed up a few years after 1999, IIRC. Also, IIRC, there didn't use to be strict rules on salary matching in trades. Whitsitt was able to assemble that Pippen Blazer team without any of the heavy restrictions current GM's and owners operate under.
in other words, the NBA isn't the same now as it was in the 90's.  It has evolved meaning the concerns of fans have evolved. NBA fan's in the 70's didn't worry about 3 point shooting either
