The NCAA moved the 3-point line back from 20 feet, 9 inches to 22 feet, 1¾ inches last season, and across Division I, accuracy from beyond the arc fell from 34.4% in 2018-19 to 33.3% in 2019-20. One possibility for this coming season is D-I teams will record a similar conversion rate for a second straight year and, indeed, for several years to come.
That's what happened the last time the line was moved back, prior to the 2008-09 season. (The 3-point line had been 19 feet, 9 inches.) It's conceivable that the sport's 3-point success rate has been, in effect, reset at a slightly lower level.
