From Nylon Calculus:
"Looking at the league-average level, the takeaway is this: an NBA team generally improves on offense by about 0.62 points per 100 possessions for each percentage point increase in its offensive rebound rate. This means that if NBA teams were to improve their offensive rebounding from 23% (where it is now) to 30% (where it was a few years ago), they would generally score about 4.3 points more per 100 possessions."

From Grantland:
"The general conclusion the authors presented at the MIT Sloan Sports Analytics Conference in March, based on data from the 2011-12 season, was that teams could net about 4 points extra per game by recalibrating their philosophy toward offensive rebounding — that teams were being too cautious."

These statistics claim that the offensive rebounding rate used in the 80's would increase today's ORtg by 4 points - and we already know that the greater transition opportunities from crashing the glass increased ORtg many more points.
However, ORtg was only 1-2 points higher in the 80's, which means that superior halfcourt defense (paint-camping, hand-checking, and no spacing) mostly offset the ORtg increase created by 2nd chance points and greater transition opportunities.
