What were the NBA's league-wide Free Throw Shooting percentages in 1985-1986 and 2005-2006?

Answer 1

If I've done the calculations properly, it looks like the average in 1985-86 was 75.6%, as compared to 74.5% last season.

To get these numbers, I used these two pages:

http://www.basketball-reference.com/leagues/NBA_1986.html

If you scroll down on each page, there's a list of team stats. I just used the "NBA Average" numbers to determine free throw percentage. I also looked at 1976, and the number was again right around 75%.
