NBA Summer School: Blake Griffin & Serge Ibaka





Summer is officially over, but NBA players still have one week left to add the finishing touches to their summer improvement before camp opens.  In Part I, we took a look at Kawhi Leonard, and the the recently extended Paul George.  In Part II, we'll analyze two heavily critiqued but extremely important big men, Blake Griffin and Serge Ibaka.

The Los Angeles Clippers and Oklahoma City Thunder will be vying for pole position in a loaded western conference this season. The Clippers added valuable role players, JJ Redick and Jared Dudley to go with one of league's top coaches, Glenn 'Doc' Rivers. The Thunder will be welcoming Russell Westbrook back after losing him in the 2013 playoffs to a torn meniscus. Both teams are firmly in the group of 8-10 franchises that have a realistic shot to win the title.  But ultimately, the fate of the Clippers and Thunder will rest on the shoulders of their 24 year old power forwards.


Offense

Blake Griffin and Serge Ibaka were very efficient offensively this past season. Both posted offensive ratings and win shares well above league average as shown in the table below.

Blake Griffin receives a lot of criticism from talking heads about what they perceive as offensive deficiency. Like most things in life, this perception is only partly accurate.  Blake's moves are somewhat mechanical and he lacks the fluidity of former legends, Charles Barkley and Kevin Mchale.  When he's not posterizing the likes of Kendrick Perkins and Timofey Mozgov, Blake's game is rarely pleasing to the eye.  But beauty and grace do not equal efficiency (ie: Rudy Gay).  He's an above average rebounder (although his rebound rate has steadily declined since his rookie season) and he gets to the free throw line at an effective rate.  But what truly separates Blake is his elite passing ability.  His assist rate* ranked fourth highest out of all power forwards and centers (behind only LeBron, J-Smoove, and Luke Walton).  He usually makes the correct pass when the doubled and rarely forces the action.  Many don't recognize Blake's passing ability, but it's one of the reasons the Clippers produced the fourth most efficient offense this past season.

Coach Brooks should increase Ibaka's offensive responsibility this year. The departure of Kevin Martin will leave a burden on Ibaka and Reggie Jackson to replace his production.  A good example for Ibaka to model is Chris Bosh.  Both have similar roles as the third banana on their respective teams and both share the floor with two high usage perimeter scorers.  Bosh's usage rate has averaged about 24% during his 3 years in Miami, and if Ibaka reaches that level while maintaining his efficiency, he could take the Thunder offense to new heights this season.

Both players are elite finishers in the painted area due to their quickness, jumping ability, and strength at the power forward position.  Ibaka shoots above average from practically every area on the court and has major potential as a stretch big with range extending to three point territory.  Blake has two main areas of improvement and neither include post play (to the surprise of many).  The first is outside shooting.  If Blake can improve on his jump shot from 10+ feet to above average levels, it will make defenses more honest about playing him with a cushion and clogging the paint.  The second area is free throw shooting.  Free throws have plagued Griffin since he entered the league (mostly due to that hitch in his stroke) and if he can improve to above 70%, similar to Tyson Chandler, he could become more aggressive late in games without concern about landing on the foul line.        


Defense

Defensively, these players are vastly different.  Serge uses his wingspan and great anticipation to block shots at historic levels.  Blake is improving defensively but doesn't always use his pogo-stick jumping ability to affect shots on defense.

Griffin posted an above average defensive rating this past season but the Clippers were 9 points worse defensively when he was on the court.  Part of his struggle was due to Griffin's lack of awareness and part of it was Vinny Del Negro's lack of a consistent defensive scheme.  Doc Rivers should be a big help to the individual development of Griffin's D.  Since the 2008 season, Doc's Celtics have finished no lower than 6th in defensive efficiency (points allowed per 100 possessions). The Clips have no one close to Garnett defensively, but if Griffin can fully commit himself to the defensive end and become even half the defender KG was in his prime, the Clippers will post a top 5 defense.  

Serge is a truly elite rim protector.  He was the second best shot blocker this past season, only behind the enigmatic Larry Sanders.  But being an elite shot blocker is just part of the equation to being an elite defender.  The other is positioning and awareness, particularly in the pick & roll, where Ibaka is improving every year.  Ibaka sometimes lacks the intricate balance of containing the ball-handler and returning to his original assignment, and that late retreat can cause major holes defensively for the Thunder.  Similar to the Heat, the Thunder are usually able to make up for late or incorrect rotations due to their elite wing athleticism and Ibaka's special shot-blocking ability.  Last season the Thunder ranked 3rd in defensive efficiency, and this was due in large part to 'Air Congo'. If Ibaka can fully realize his potential and improve his pick & roll coverage, the Thunder will be the best defensive team in the league this season.

Both of these young studs will play a major role in how far their teams advance.  How much closer are the Thunder and Clips to overtaking the Spurs out west? Only Ibaka and Griffin truly know.

NBA Summer School: Kawhi Leonard & Paul George



The offseason is the most valuable time of the year for many NBA players. The time between July and September is when NBA players can improve their game before the start of a new season.  Summertime is when players make a leap from solid to good or from good to great by putting in the necessary hard work. The summer was when Jordan sculpted his fadeaway and when Kobe met with Hakeem the Dream to add post moves and improve footwork.  This is a time that players will either waste or use for individual development.  Over the next few weeks, I'll evaluate some of the most promising under-25 players and look at areas for improvement both offensively and defensively.

Today, we'll look at two of the best small forwards in the league, Paul George (23) and Kawhi Leonard (22).

Offense

Paul George and Kawhi Leonard are major components to championship contenders and each came very close to raising the trophy last June. The following chart shows how they compared in a number of offensive categories this past 2012 - 2013 season.    

from Basketball-Reference.com

The Four Factors, or  "Four Factors of Basketball Success" are the four statistical categories that hoop analytics godfather, Dean Oliver, found that most contribute to NBA success.  Paul George shot at a league average clip of 49%, while Leonard shot an elite 56% eFG% in 2013 (in comparison, Kevin Durant also had an effective field goal percentage of  56% in 2013)*. 

Both players are solid rebounders for their position, and get to the free throw line at an average rate. George had a poor turnover rate while Leonard was better than average, but this can be partly attributed to their respective roles.  George had a bigger role on the Pacers this past season, in large part to Danny Granger's season long knee trouble.  George had to create offense for Indiana all season and quickly adjust to being option #1.  Meanwhile, Leonard was able to take advantage of his smaller role with the Spurs by focusing more on finishing and less on creating plays for his teammates.   

Paul George's offensive rating was right at league average (104), which was mainly due to his high turnover rate and average shooting numbers.  The Pacers should have more firepower this upcoming season with the return of Danny Granger and the signing of Luis Scola, and both will likely reduce the offensive burden on George.  Better shot selection (more on this below) from George and less ball handling responsibilities should greatly improve the Pacers offense this upcoming season.  

Leonard had an excellent offensive rating in 2013 due to his low usage and his elite shooting numbers.  The Spurs could benefit from giving Leonard a larger role in the offense and limiting the usage rate of the aging and less efficient players such as Manu Ginobli and Gary Neal (who is now on the Milwaukee Bucks).

The chart above shows the shooting stats by location for each player.  Both players finish at the rim very well due to their elite athleticism and improving skill.  They both shot at a league average clip from three, but George could benefit from limiting the number of long two's he attempts (especially from 16-23 feet, the least efficient area on the court).  Both players should increase the number of attempts in the paint and at the free throw line by using their elite quickness and leaping ability to put more pressure on the defense.  Lastly, increasing the number of three point attempts (especially from the corners, the most efficient area on the court) can help both players improve offensively this upcoming season.


Defense

What truly makes these two special is their defense.  Besides LeBron and Tony Allen, these may be the two best perimeter defenders in the league.  They each have great lateral quickness and active hands.  The following chart shows a few of their defensive statistics from last season.    

from Basketball-Reference.com

George and Leonard had almost identical steal rates due to their great anticipation of passing lanes.  What stands out from watching film of both players is how many deflections they rack up and how well they move laterally to stay with their defensive assignments.  Both areas are difficult to quantify with available stats, but the recent news of motion tracking SportVU cameras will soon change this.

Overall defensively, both players are stellar, with Leonard rating seven points below league average and George ranking even better at nine points stingier than average.  There aren't many areas of critique for either player other than to add muscle to their slight frames in order to bang with larger forwards such as LeBron James and Carmelo Anthony.  Both players have room to grow and if they do, should improve their team's chance at hoisting next years Larry O'Brien trophy.
