most efficient play in basketball, with an expected point value of like 2.4 (for an 80% FT shooter). Nothing else comes close. Shooting 40%+ from 3 yields expected value of 1.2 points. You have to shoot 60% from 2 to get the same impact, which you can do and then some, IF you are getting open layups/dunks.
Thus the goal of every offense needs to be to generate corner threes (the easiest 3-point shot) and layups/dunks (which you can shoot at a 60-80% clip if they are pretty open). Make the defense pick which of those it wants to give up.
