There are two screens
One at the 3 point line (Asik)
One at the foul line with another 3 point post player (Patterson)
You screen 3 ppl with 2 bodies + you get better positioning for rebounds.
If Harden gets Doubled, you tell Harden to sit down. They'll have to either sit their lockdown defender or keep playing. You wait for second half, and you unleash a fully rested Harden on them.
If they are doing to much damage or if Lin can't play make that night or keep it close enough, you put Harden back in and you run Triangle. You give up offensive rebounds but you can tire out the defense easier that way.
this isn't rocket science ppl.
