This has been said 15 different ways from Sunday, but I'm going to attempt a conciser version:
Daniels shoots the three flat footer, like a long free throw, and his catch-set-shoot time is very long relative to the average player. He has the length and strength to shoot 3s flat footed and hit them. But it means that he does not get the shot off quickly, and he can't rise up over closing defenders, a la Ray Ray. If a defender is in front of DD, DD will generally not shoot the 3.
Giffey shoots a standard jumper from 3, but he prefers to have his feet set when he catches the ball. Further, similar to DD, his catch-set-shoot time is relatively long, and, accordingly, he doesn't like to shoot over defenders who are in front of him or who are closing rapidly.
Together, neither guy can head and shoulders fake a move on a set defender and then shoot the 3 effectively.
Further, neither guy can set up a 3 with a dribble, fake a guy with a crossover or a fake drive and pull up.
Finally, neither guy can roll off a screen, catch a pass while moving, plant both feet and shoot in one fluid motion with a defender rolling around the screen or trailing.
In effect, both guys need to be set when they receive the shot and both guys need to have space. That severely limits their effectiveness from long range, and it allows defenders to cheat off of them further than they could if either guy had a quick catch-set-shot jump shot from 3.
Omar, BTW, has a much, much quicker release than either guy. Ironically, said Omar release speed is completely negated by him shooting from his .
