My thinking was an increase of 17" would initially lower 3PT shooting % of players with possibly lowering the % of 3PTA by teams. Going by the below numbers from some of the previous 11 years after the 12" distance increase to start the 2008-09 season, expect both the above scenarios to occur. Especially considering this time an added 5" increase over the 12" from 2008.
Look at the median team point for the 2007-08 college season when the distance was 19-9. The median point D1 team shot 34.9% from deep. The median point D1 team's shots consisted of 33.9% being 3PTA. In 2008-09 when the distance went to 20-9 the median point lowered to 33.9% for teams 3PT shooting along with less 3PTA shots at 32.9%.
With that 33.9% of teams 3PTA from the last season (2007-08) with the line at 19-9. Well it wasn't until 2015-16 that the median team point went above 33.9%. Appears coaches were hesitant to keep shooting so much from deep. Also that median point 34.9% team 3PT% shooting from the same 2007-08 season. Well in the last 11 years it has never been surpassed. So the past numbers say that 17" increase will decrease both 3PT% shooting and 3PTA% this season. Probably easier to look at it below.
