The median teams score around 82 points per game in my D-leagues. This season, the medium D-league team scores around 108. NBA teams have a median of around 106. So not realistic at all to only have 82 (with a high of 88).
I'm pretty certain this is due to the SCORING ratings of D-league players being so low. No one is talking shots because their ratings say they can't. There are gunners in the real D-league, but NONE in DDS.
This is more cosmetic than substantive, however real D-league games have more scoring than the NBA, not 25% less.
