I think opposing teams are coached to take a lot of 3s as well as try to drive the paint against them based on early success this season. The lack of perimeter size and disruptive hedging that was a strength the past 2 seasons is part of the reason for the 3 Pt success against us.
With that said, I think it's a bit of a fluke teams are hitting 3s at the pace they have been. I think as the season goes on, teams will have stretches where their 3s aren't falling, especially if our motion offense is run quicker and better wearing teams down. Tired defenders tend to struggle shooting 3s so they need to make the other team's shooters work harder on that end of the floor. Note that X played some stretches of zone that likely helped keep their legs a tad fresher.
