If defending the 3 was easy, the Warriors wouldn't be off to an 18-0 start. It has been nice to see our team join the 3 point party this year (though I miss all those dunks from Gabe and Aaron).Around 28% 3 point shooting for Iowa opponents. I would say that is pretty good.
As a comparison, Iowa shoots better than 40% on the year.
3PT defense is almost entirely a function of luck
