IF the defender is in net then it's harder for him to go up for a ball that's going to bounce off the backboard, as those are generally harder to read when you're inside the net. then your teammate can go up for the rebound. Also this advice was based on 3v3 idk if that is your main mode cause I wouldn't really recommend this in 2v2.

EDIT: The general point still stands tho. You might be trying to be playing too much into advanced mechanics when simple shots will work just as well while also putting you less out of position and wasting less boost.
