Efficiency in 2000 playoffs was 80 points per 100 possessions. This year's playoffs, offenses have an offensive efficiency of 115 to 120. A lot of that depends on made threes. The variation can be huge from one game to the next.
The average number of games decided by a blowout (categorized as winning by 20 points or more) is 28%. In 2018, it was 20%. Funny thing is, the average margin of victory this year is 13 ppg where in 2014 it was 11. Just interesting things.
