Deng and are 3 point threats. They may not be hitting their shots this season but these dudes once averaged 40% in a season. Sure the percentage dropped this year, but I dare anyone to leave these two wide open from three.
Don't this is entirely accurate, or at least a good accounting of Deng and Iggy.
Deng career number: 33.6% from 3
Career Best: 2009, 40% from 3. But, he only attempted less than 1 3pt shot per 2 games.
More realistically, Deng is around a 35 or 36% shooter from 3, if he's taking 2 or more a game.
Iggy's career number: 32.9% from 3
Career Best: 2012, 39.4% from 3, 3.1 attempts per game
Iggy is a bit more of a mystery, but it is the most likely that last season's shortened NBA season was an outlier, not the norm for Iggy. 34-35% from 3 if he's taking more than 2 a game.
Couple that with Monta Ellis's 23.5% from 3pt range on 3.5 3PA's per contest, your offense indeed has real issues with spacing and efficiency.
