According to a release from the NCAA itself, the three-point line is moving back (again). When I was first pestering my dad to pull the ball back out of the peach basket for me, the length was 19' 9". That changed in 2007, when they moved it back by a foot to 20' 9". Threes kept dropping at increasing rates, so the line is scooting back to 22" 1¾", which I imagine is a round number in metric.
Xavier wasn't exactly lighting the world on fire from deep last year, and this is another confounding factor to that. Hoped-for increases in three-point efficiency from Naji Marshall and Quentin Goodin will now be that much more difficult to come by, and grad transfers Jason Carter and Bryce Moore also feature the three-point jump shot as part of their arsenal.
You would expect the adjustment to be even more difficult for incoming freshmen, who now have to find nearly two and a half feet of additional range on their three-point shot. Expect Kyky Tandy and Dahmir Bishop to be the most affected from Xavier's 2019 class.
