To Noah's defense....
Dak threw the ball before Noah turned his head, so when Noah turned to look for the ball, it was on him within a half of a second. So the drop was likely partly due to not reacting in time to catch it.
With such a short pass, Dak could have waited one more blink for Noah to turn his head. So this is a risk Dak took, then it bounced off Noah's hands (but not because he can't catch), and the rest is history.
Yes, Noah still could have caught it, but Dak lowered the chance of a catch by throwing such a short pass with the receiver not looking yet. Hard to track the ball in half of a second. Look at the play in realtime, not in slow-motion...that was not an easy catch.
