watch videos of the "old" games before the 3-point line. When teams played zone defense, it was not uncommon for all five defenders to have at least one foot in the lane.

Today's game rewards guys who can shoot. It also values teamwork (screening, cutting, and passing) to get shooters open for those shots. It values "big guys" with basketball skills (e.g. Blackshear) over big guys who merely clog the lane.
