Boston Celtics Quick Three Set Play

Here I would like to share with you an easy set play of Boston Celtics, that is used by them to get two different 3pt shoot options at the very beginning of the set.

Firstly 2 slides down to under the rim.
Secondly 3 slides down to under the rim
as well.

Then 3 and 5 set staggered screens for 2
who comes off hard the screens to the right
wing. Later 4 sets a down screen for 2 who
moves to the left wing. 1 can pass to 2 or to
3 to get two quick 3pt shoot.
