How to Fix Harden-Lin (Lost) Connection




Harden and Lin were the best backcourt duo in the 1st 2 games but gradually lost their connection in the next 6 games (decreasing both of their performance) when Lin deferred the primary playmaker and distributor role to Harden. As a result, both of their performance suffered in the next 6 games.
After Houston Rockets 2-0 start with 21.4% Lin Usage Rate, they lost 4 of the next 6 games with Lin's Usage Rate dropped to 16.6%. Lin's AST/game to Harden and both 3PT% also dropped. Lin needs to take charge of the PG role.

How do we know it's true? In this short analysis, I will show that these general observations from many fans watching the game are validated by the statistics of lower 3PT%, worse +/- and Lin's lower usage rate (USG%) 3PT% in Game 3-8 which also pointed to the lack of ball movement expressed by Houston coaches. Houston coaches would need to right the ship by insisting Jeremy Lin to be the primary playmaker and let Harden be the best scorer.

After starting 2-0, Harden and Lin were speculated to be the best backcourt duo in the NBA.
But not so fast because they crashed back to earth with 4 losses and 2 wins in the next 6 games


  1. Worsening trend of  +/- Stats
Worsening Team +/- Stats in the last 2 min of regulation
Even in their last 2 wins, their +/- stat in the last 2 min of the regulation showed that they were outscored by their opponents unlike the first two games when they finished stronger by outscoring the opponents.  Houston is a young team who didn't know how to close out games yet but the evidence (albeit small) said they managed to do it in Game 1 and Game 2. Most knowledgeable Houston fans know that the individual iso plays in the last few games simply did not work.

 The individual +/- Stat for Lin and Harden also shows similar but worse trend for Lin after Game1-2.


Why? They couldn't finish strong because Lin deferred to Harden to be the primary playmaker.
Harden is a great playmaker but he only got to play with his teammates for over 2 weeks and he can't do it all by himself. If this continues, he will overexert himself on the offense and unable to help much on defense. Meanwhile, Lin will be unable to distribute the ball effectively  on offense. The whole thing will snowball.

If you are still unconvinced, check also the decreasing trend of # of assists from Lin to Harden from Game 3-8:

Harden simply had to work harder for his points and the results were worse than Game 1 and Game 2. Even if Game 1 and 2's opponents were weaker team, the downward trend is very alarming.


  1. Plummeting 3PT% for both Harden and Lin
Fans who watched the games can tell that Harden seemed to play the Point Guard role and
Lin just seemed content to let Harden be the primary playmaker and assumed the role of standing in the corner as a spot-up 3-PT shooter, which is never his strength. As a result, their 3PT% plunged from 43% and 40% to atrocious 17% and 21%.


 But defenses double-teamed Harden in Game 3-8  so he can no longer score 37 points and 45 points like he did in the first game. Lin's performance suffered because he penetrated less and his FG attempts dropped because he did not seem confident  to shoot and being a still-standing 3PT shooters in the corner.

  1. The Usage Rate % (USG%) validated that he deferred too soon by giving the ball on offense to let Harden be the primary playmaker in Game 3-8.
Usage rate tells us the number of possessions a player utilizes while on the court. This statistic is a good indicator of how big of a role a particular player has in the team's offense.

His Usage % dropped from 21.4% to16.4% from Game 1-2 to Game3-8 while Harden's Usage % stayed roughly the same around 30%

You might be curious on what their USG% in 2011-2012 season when they played for NY Knicks and OKC Thunder.

For Lin, it was significant drop-off by 50% from 31% to 16% in Houston. Yes, it's a different system for Lin where it was point-guard heavy in NY Knicks under Coach D'Antoni but later on Coach Woodson also took over without much change in 31% USG% so Lin was always involved for both NY coaches.

Harden was the 6th man in OKC Thunder so he deferred to Durant and Westbrookto only have almost 20 USG%. Now he is a starter so he certainly should increase his USG% but Houston coaches need to ensure that Lin will be the primary playmaker as evident in Game 1-2.

This would explain why Jeremy touched the ball less on all possessions and seemed to lose confidence in shooting rhythm. He is not a 3PT specialist like Steve Novak who excels in catch-and-shoot. He needs the ball in his hands in most possessions to leverage his strength to penetrate and break down the defenses or bring it back out if defense collapses on him. I will provide some examples in the next posting to illustrate this point.

USG% of 22% seems optimal for Dragic and Lowry under Kevin McHale's system
Some will say that Coach McHale's system will require different USG% for the point guard.
Then let's check Goran Dragic's and Kyle Lowry's average USG% rate from last season
Dragic and Lowry had similar USG% at 22% under Coach McHale's system so this offers more argument that the coaches should expect Lin to maintain the same 22% USG rate to be as effective as in Game 1 and Game 2.

I understand Jeremy Lin is still recovering from his knee surgery and haven't regained 100% of the explosiveness but he demonstrated he can be the primary ball handler in Game 1 and Game 2 to leverage Harden's strength. So why changed the winning formula? Why made both Harden's and Lin's performance suffered in Game 3-8 by making Harden the primary ball distributor?
Harden seemed to score 40 points with effortless shooting in the first 2 games, but now he had to assume the most PG role with increased attention from defense while Jeremy is stuck on the corner.

In summary, the key message to Houston coaches is loud and clear:
Allow Jeremy Lin to be the primary playmaker and ball distributor to facilitate ball movement. He is the Point Guard after all. He will leverage Harden's strength as top scorer and secondary playmaker as proven in Game 1 and Game 2. And monitor the Lin's Usage Rate % to be at least 22%  (similar to Dragic and Lowry in McHale system) to support their desire for more ball movement.

Jeremy Lin is an Excellent Defender


Proof that Jeremy Lin is an Excellent Defender

Is Jeremy Lin an excellent defender or just an average defender? At times, he seemed to leave his man to help his teammates on defense and he gets burned when his man made layup or an open 3PT.
DWade had the highest PPG at Houston since 1986-1987.
He had 19 pts on 8-18 FGM-A.
In this 8-3 run, Jeremy's defense contributed to 2 missed FG with tight defense and 1 block, and forced him to give up the ball once.  
In the 11/12/12 game against Miami Heat, Jeremy sparked the defense in the 3rd quarter to start a 16-9 run to tie the game at 75-75 when he was substituted. He actually had a major role in the 8-3 run before Harden played PG to close it with 8-6 run.

In the 3rd Q with 7:43 remaining, while trailing 66-59, Houston made 16-7 run to tie at 75-75
Lin played a major role in playing team defense and orchestrating offense to make 8-3 run with excellent ball movement (average passes per possession =3.4). The score was 67-69 with 5:10 remaining
Then Harden played a major role to orchestrate a 8-6 run but the ball movement was poor (ave. passes/possession = 1.2)

We will look in detail in this 8-3 run, especially in how Lin successfully guarded Wade, Bosh, Cole resulting in 1 block, 2 missed layups, 1 steal, 1 charge. This is not the work of an average defender.
He made 1 mistake of leaving Chalmer for a wide-open +3 after deciding to help guard Ray Allen.
On offense, he scored one 3PT, 1-2 FT, 1 assist. The rest of the time, Harden played PG with mixed results and worse team defense.

For analysis purpose, I will reward GOOD and BAD defense points to analyze Jeremy's defensive impact on the 8-3 run.

When Lin managed to play defense well to prevent a player to score, he is rewarded +2 or +3 (a failed 3PT). If he fails to prevent his man from scoring, he will be penalized -2 or -3 (a made 3PT) or -1 (fouling someone to prevent from scoring)

In this 8-3 run, Lin's Total GOOD defense points are +10 and Total BAD defense points  are -3

7:52
1st POSSESSION
Lin was left one-on-one to guard Dwade on a fastbreak. Lin made Wade throw up bad layup and missed
 (LIN's  GOOD man-to-man DEF defense unrecorded in boxscore +2)



Asik could not hold the rebound and it went out of bound.
Harden couldn't guard DWade and had to foul him. Wade missed both FTs
 (Harden BAD defense -1 penalty since Wade did not make any FTs)




2nd POSSESSION
3-0 Lin made a wide-open 3PT shot. Ball movement= 4 passes. (LIN  OFF +3PT)
3-3 Lin left Chalmers to guard Battier. Bad mistake. Chalmers made 3PT (Lin BAD defense -3 )
       Lin's Total GOOD defense points = +2 and Total BAD defense points = -3

3rd POSSESSION
4-3 Lin drew foul on Chalmers. Made 1-2 FT. Ball movement= 3 (Lin  OFF +4PT)


 
     Delfino subbed for Asik.
4-3 Lin made Wade change his layup and pass to Battier,  (LIN's  GOOD DEF defense unrecorded in boxscore +2)
       got rebound off Cole's airball
       Lin's Total GOOD defense points = +4 and Total BAD defense points = -3





4th POSSESSION
6-3  Harden-Lin-Harden-Parsons  resulted in Parsons getting fouled and made 2 FT. Ball movement = 3 passes.    
6-3 Lin stole the ball from Bosh leading to quick pass to Parsons (Lin  DEF 1 STL)
       Lin had a good spacing between Cole and Bosh and decided to swipe the ball from Bosh.
       Lin's Total GOOD defense points = +6 and Total BAD defense points = -3




 5th POSSESSION
8-3 Parsons made easy dunk off Lin's well-timed bounce pass (Lin OFF 1 ASST)

        Lin and Delfino challenged Wade's layup (possibly a block) and Wade missed (LIN's  GOOD DEF with block +2)
       Lin's Total GOOD defense points = +8 and Total BAD defense points = -3





6th POSSESSION (HOU trailing 67-69)
      Harden's pass got deflected by Cole. He could have passed it back to a wide-open Delfino

      Parsons missed layup.  Ball movement = 6 passes. Good attempt but good defense by Battier

   Norris Cole offensive Charge (Jeremy Lin draws the foul)(LIN's  GOOD DEF good team defense unrecorded in boxscore +2)
       Lin's Total GOOD defense points = +10 and Total BAD defense points = -3


This mini 8-3 run demonstrated that Jeremy Lin is an excellent man-to-man and help defender in guarding 3 different players (DWade, Cole, Bosh) preventing them to score. He produced  1 block, 2 missed layups, 1 steal, 1 charge. But he also made one mistake against Ray Allen by leaving Chalmers for an open 3PT shot. He should stay aggressive in defense and get better in reducing mistakes with more experience in not overhelping with team defense against smart players like Ray Allen.

Interestingly, Harden passed the ball back to Lin 3 out of 4 times and good things happened when Jeremy decided to attack the basket or shoot the ball. On the offense, Jeremy should stay aggressive to attack the basket and/or pass to any open teammates.

Harden's bad plays seem to be when he decided to play hero ball to take it strong to the basket without any ball movement as proven by the last few possessions in the 4Q when Houston gave up the lead in the last 3 min.
