Watching Liggins, he has no interest in shooting 3s it seems to me... Off the catch when the defense is scrambling he doesn't even look at the rim.
But I was looking through his stats and in the DLeague last season he shot 43.4% from three, and that was even on 4.21 attempts per game over 34 games... so that's a decent sample size.
I'm also curious as to whether the majority of these were off the catch. He played along with Rodney McGruder quite a bit in the backcourt who I wouldn't expect to be much of a shot creator, but Liggins had just a 18.4% usage rate.
I looked through more #s, and found that of Liggins's 143 three point shot attempts last season, 127 of them were from above the break. (Though his %s are fairly consistent among all 3pt spots). For reference, about 74% of JR's 3 point attempts last season were from above the break. That's significant if Liggins is to take JR's role if he's forced to miss time.
Unfortunately I can't find catch and shoot DLeague numbers anywhere.
Also, over 95 career DLeague games (2012-13, 2013-14, and 2015-16) he shot 38.0% on 4.68 attempts per game.
In the preseason he was 1 for 5 from three. 0 attempts in regular season this year.
