The Spurs “Weak” Action
In their championship days, Spurs opponents could expect a steady diet of Tim Duncan post ups. As the NBA became more perimeter oriented, Gregg Popovich adapted his offense to incorporate the talents of his own perimeter players. This year the keys to the offense have been turned over to Tony Parker, and the Spurs have responded with the highest offensive rating of any team in the regular season. While this years’ Spurs are best known for their relentless pick and roll attack, Popovich has not abandoned the fundamental motion principles that have carried his teams to championships in the past. One of these motion plays is known as “weak,” and the Jazz saw a steady diet of weak in their first game with the Spurs.
The play begins with the ball handler (here Tony Parker) passing ahead to the strong-side wing (Manu Ginobili). This pass keys several actions:
1. After passing ahead, the ball handler cuts across the lane. The strong-side wing looks to hit the ball handler as he cuts through:

Here, the crafty Ginobili perfectly times the pass and hits Parker in stride for the layup.
2. If the ball handler can’t be hit, the strong-side wing passes up top to the trailing big man. The trailer then swings the ball to the ball handler, who cut through to the weak-side of the floor.
3. As the ball is swung, the weak-side wing goes to set a cross screen for the other big in the post:

As the ball is swung to Tony Parker, Ginobili (this time at the weak-side wing) sets a screen for Duncan in the post. Al Jefferson cheats over the top of Ginobili’s screen, leaving Duncan wide open to catch the lob from Parker.

We see the pass ahead and cut through the lane, keying weak. This time the cross screen is for Boris Diaw, who is able to seal his defender on the opposite block. Boris quickly feels his defender on his right shoulder, then unleashes a baseline spin for the easy reverse layup.
The post man can also come off the cross screen to set a ball screen:

After the cross screen, Duncan chooses to set a screen for Parker. Parker waits for Duncan then quickly step fakes his defender into the screen. Parker then crosses over away from the screen past the help of Al Jefferson. To prevent an easy basket, Paul Millsap is forced to help from the weak-side corner, leaving Kawhi Leonard wide open for three.
In all these clips, we see the fourth action of weak, a screen-the-screener action.
4. After swinging the ball back to the ball handler, the trailer comes down to set a screen for the weak-side wing, who just set the cross screen for the post.
In this next clip, we will see the Spurs run a counter of this action that still leads to a screen-the-screener for the ball handler instead of the weak-side wing:

We see Parker pass ahead to Gary Neal and cut across the lane. Instead of cutting all the way to the weak-side wing, he doubles back to set the cross screen. Meanwhile, the weak-side wing (this time Stephen Jackson) pops out to receive the swing pass from the trailer. After swinging the ball, the trailer (this time Matt Bonner) screens-the-screener allowing Parker to come up to the top of the key and receive the ball.
In the last clip, we will see another counter from the weak action:

Parker passes ahead to Danny Green and cuts across. We see the weak-side wing Stephen Jackson move down, but he sets a back pick for Parker instead of screening for Boris Diaw in the post. Parker comes off the back pick towards a waiting Boris Diaw, who is ready to set another screen. Paul Millsap is so concerned with denying Parker that he leaves Diaw a direct line to the basket. Diaw cuts back door and Duncan finds him for an easy layup.
With weak, the Spurs have an equal opportunity play that can naturally flow from screens, to off the ball movement, to post ups, to pick and roll. Players have no fixed positions and Popovich gives them free reign to read the defense and react accordingly. The ability to execute a variety of options with varying personnel, combined with the Spurs great patience and unselfishness, ensures the offense can generate high percentage shots: both in the past – when Duncan was the anchor on the block, to today – with Parker speeding around the court.
