How Top Point Guards In The Pick And Roll Are Defended…And Why


 NBA Playbook.com

When I did my post on Rajon Rondo for Basketball Prospectus a few weeks ago, HoopSpeak‘s Beckley Mason (seriously, go follow him now) mentioned that he thought it would be interesting to look at how other top point guards were played in the pick and roll.  Considering that I agree with Beckley, I decided to look at five of the league’s top point guards and see how defenses play them.
Why is this important?  With the influx of a lot of great point guards, the pick and roll has been featured more and more in the NBA.  The reason why the pick and roll is so effective with a good point guard is that it forces the defense to react and puts them on the backfoot.  That’s why you see defenses trying to stop the pick and roll in a lot of different ways.  One of the things that I did notice when focusing on the defense is that they tend to try and force the ball handler coming off of the pick away from his strength and towards his weakness.

Rajon Rondo

How Teams Defend Him

Teams defended Rajon Rondo by going under screens.  Out of all the ball screens that Rondo received, the defense went under the screen 50% of the time.  In addition, Rondo was rarely trapped coming off of the screen, as defenses trapped Rondo 0.8% of the time, or 12 total traps.

Why?

When playing Rajon Rondo, you want to turn him into a shooter and a scorer.  Rondo is such a great passer and there are so many other great scorers on his team, that you don’t want to dedicate extra defenders to Rondo as he comes off of the ballscreen:




Rondo is a really heady point guard and when he sees a trap when coming off of the ball screen, he is immediately looking to stretch the defense, find the open man, and hit them.  With the kind of success he has being trapped, it is no wonder why you see so few traps of him.

One of Rajon Rondo’s weaknesses, and perhaps his biggest, is that he is not a good shooter off of the dribble.  Not only does his struggle with his shot, but he also lacks the confidence to take a jumper off of the dribble consistently to make himself a threat.  As a response teams go under the screen, pack it in, and force Rondo to beat them.  The result is a higher amount of turnovers you would expect as Rondo tries to force things instead of taking the shot:





When watching Rondo come off of a ballscreen, you really see his unwillingness to even look at the rim, let alone attempt a jump shot.  With Rondo not being a threat to shoot the basketball, it invites teams to go under the screen because they know that he won’t hurt them with the shot.  It allows defenses to focus on defending the four other Celtics while keeping Rajon Rondo from getting into the paint and breaking the defense down. 


That’s the goal.

Derrick Rose

How Teams Defend Him

Teams defended Derrick Rose by trying to get the basketball out of his hands.  When coming off of a ball screen Rose was single covered, meaning there wasn’t an extra defender sent his way, just 34.8% of the time.

Why?

Rose’s situation with his Bulls is almost the exact opposite situation that Rajon Rondo has with the Celtics.  Rose is so good with the basketball in his hands that defenses would much rather let Rose’s teammates try to beat them.  To do so, they throw extra defenders at him and make Rose pass the basketball.  When defenses committed to Derrick Rose, they were able to force him to pass it 91.3% of the time and on those passes, his teammates scored only 0.946 points per possession on just 43.6% shooting:





As Rose comes off of a ballscreen, he more often than not sees a second defender looking him right in the face as teams overload in his direction, leaving teammates open and willing to deal with the consequences.  

Rose is a smart player and he doesn’t force the issue a whole lot, so teams were able to get the ball out of his hands more often that not as Rose made the right direction, hitting the open man.  Unfortunately for Rose and the Bulls, his teammates couldn’t knock down the open shot consistently.  That end result is a much more attractive option than the end result when Rose is single covered, usually coming off of a switch with a big trying to defend Rose:






Derrick Rose is so quick and so explosive that if he sees an opening, which usually happens when he is single covered coming off of a ball screen, he attacks it before the defense even knows that it is happening.  Once Rose gets to the rim he is almost impossible to stop and when watching him attack the pick and roll so successfully, it is no wonder why he is getting double on most ball screens.

Steph Curry

How Teams Defend Him

Teams defended Steph Curry by going over screens in an effort to force Curry to attack the rim instead of taking the jump shot.  Teams have gone over Steph Curry ball screens 62% of the time, 9th most in the NBA among all ball handlers with at least 60 pick and roll possessions.

Why?

Steph Curry is probably one of the best, if not the best, shooter at the point guard position.  Because of that, teams want to try and keep him from getting open looks coming off of ball screens.  To do that, defenses went over ball screens forcing Curry to put the ball on the floor and attack the rim instead of stopping, pulling up, and knocking down jumpers.  Something that happens when the defense goes under ballscreens:




With the threat of that happening, teams want to try and stay attached to Curry.  The only way to do that is by going over ballscreens:




When the defense goes over a ballscreen against Steph Curry, they are keeping pressure on him, not allowing him to get an open look, and forcing him to keep his dribble going.  The result is usually either a turnover or an uncomfortable/contested lay-up or shot in the paint.  Those are shots that Curry struggles with, especially when compared with his jumpers when his feet are set.

Steve Nash & Chris Paul

How Teams Defend Them

When looking at pick and roll point guards, Steve Nash and Chris Paul are probably the two most complete point guards in the NBA.  That becomes obvious when looking at how teams try to defend them.  Unlike the three previous point guards, where there was a noticeable trend when looking at how they are defended, there is no one way Nash and Paul are defended.  When it comes to Chris Paul, defenses went over screens 36.3% of the time and went under screens 35% of the time.  With Nash, the numbers were a little more skewed towards going over the screen, but even still, defenses were attempting to mix it up against him as defenses went over the screen 42% of the time and under the screen 22% of the time.  If there is one trend in regards to how they are defended it is how often they force the defense to run into the screen.  Both Nash and Paul were able to get the defender to run into the screen close to 50% of the time, as Nash did it 49.9% of the time (9th among PGs) and Paul did it 54.7% of the time (3rd among PGs).

Why?

Because both Steve Nash and Chris Paul can pretty much do everything required of a point guard in pick and roll situations, they can shoot the ball, attack the rim, and hit the open teammate, defenses are forced to try a lot of different things and they tend to not have much success trying to stop them (both PGs are among the top 12% in terms of pick and roll PPP).  In addition to this, both point guards simply know how to set up screens, as shown by the percent of time they are able to get defenses to run into screens:




When watching through these clips, it is pretty easy to see why both Steve Nash and Chris Paul are so dangerous when using ball screens.  They just know how to set up and use ball screens, putting a lot of pressure on the defense.  Their respective shooting ability forces the defense to try and go over the screen, but they are able to get their defenders to run into screens and free them up.  Both Nash and Paul are nearly impossible to defend in the pick and roll.


Looking at the 5 point guards chosen for this post, you should notice that each point guard is probably the best in their respective category.  Rondo is a great pass-first point guard, Rose is that super athletic point guard who wants to get to the rim, Steph Curry is a great shooter, and Paul/Nash are complete point guards (at least offensively).  Within each category, you can see how the defense tries to play the pick and roll, trying to play each point guard away from their strength and towards their weakness.  The only exception is with Nash and Paul, who don’t really have much of a weakness in the pick and roll, the uncertainty leads to defenders getting run into screens more often than not.
