With yet another NBA trade deadline coming and going, a lot of excitement and hope was generated among the fans and media. Some teams were looking for that final piece that makes them championship material. Others simply were looking for a player that helps them get into the postseason. Lastly, there were a few who look at this time of the year as the highlight of the season as their team struggles to even be competitive on a nightly basis so might as well position themselves for the upcoming lottery. Whatever the reasons, all fans hoped their team would have made a trade or two that improved future prospects. Question is, how often can these deadline deals really be coined successful?
Against all odds, it appears the Memphis Grizzlies are no longer one of the worst teams in basketball this season. Wednesday’s overtime victory against the Cleveland Cavaliers showed exactly how far this young team has progressed since last year. As evidenced by his performance against the Cavs, Zach Randolph (34 points on .526/1.00 percent shooting, 1 three on 1.00 percent shooting, 14 rebounds including 7 offensive boards, 2 assists, 4 steals, 1 blocks and 1 turnover) has emerged as one the Grizzlies’ primary weapons and leaders on the court.
Gulp.
Anyone who watches basketball knows that over the years, Randolph has accumulated quite a rap sheet from his off the court antics. Shoplifting, battery, underage drinking, fighting with teammates, driving while under the influence of marijuana, reckless driving, etc. On the court, Zandolph has also built up a solid resume of selfish play and boneheaded mistakes that has caused him to bounce around since the Jailblazers era. He is a lock for 20 and 10 almost every night but his quest to “get his” has often come at the expense of wins for his teams.
Exhibit A: Worst. Possession. Ever.
On young teams, veteran leadership is crucial to team success. At 28 years of age on one of the younges teams in the league, Randolph has to be considered a veteran leader, for better or worse. Take a look at the ages of the other starters for Memphis: Mike Conley (22), O.J. Mayo (22), Rudy Gay (23) and Marc Gasol (25). In addition, the rotation also includes two rookies in DeMarre Carroll(23) and Hasheem Thabeet (22), second-year project center Hamed Haddadi (24) and fourth year point guard Marcus Williams (24). The only other main rotation player older than Randolph is Jamaal Tinsley (31) who also comes with his own set of on and off the court baggage.
When a front office takes such a young and promising roster and makes Randolph the primary veteran leader on the floor and in the locker room, it raises more than a few eyebrows. Most people (myself included) expected an absolute train wreck from day one. In reality, just the opposite has occurred. The Grizz so far have improved their winning percentage from last season (.293 in 2008-09 compared to .429 this season). They’ve managed to win eight out of their last twelve games including wins over quality opponents such as Cleveland, Dallas and Portland.
But why should we think Randolph is a major reason for the Grizzlies’ success this season?
First, the Grizzlies have had a relatively stable roster since last season with Z-Bo being the main addition. The Grizzlies added a couple of rotation rookies via the draft this offseason, but certainly not immediate impact players, like Tyreke Evansor Brandon Jennings. The Grizzlies also dabbled in free agency, including Jamaal Tinsley and Allen Iverson(spectacular fail), and trades (Z-Bo). But Memphis’ main core was largely intact. Last season, the combination of Mayo, Gay, Gasol, Conley, Darrell Arthur and Haddadi accounted for 64 percent of Memphis’ minutes. This season, that same crew is responsible for 58 percent of the Grizz’s minutes, with the difference being Arthur’s 7 percent out of the rotation due to injury. Randolph represents the single biggest addition this season and has logged 15 percent of the team’s minutes.
Second, there has been a strong correlation between how Randolph performs and whether the Grizzlies win. It seems that every team has at least one “barometer” player that they depend on to play well in order to win basketball games. For example, for the Suns it is Jason Richardson; for the Thunder it is Jeff Green. For the Grizzlies this season, it has been Zach. In the ten games in which Randolph has tallied twenty or more points, Memphis is 7-3. Clearly there is some anecdotal evidence supporting the claim that Randolph is a major reason for why the Grizzlies have improved this season.
So what does Randolph bring to the table and has his game changed this season?
Randolph brings a legitimate scoring threat from the four position, which the Grizzlies sorely lacked last season. It is also important to note that Z-Bo can create his own shot in iso situations, which again Memphis lacked from it’s big men ranks. About half of his shot attempts are jump shots and half are close (at the rim and tip-ins). His close attempts are largely a result of his excellent work on the offensive glass (ZR currently ranks first in total offensive rebounds and fourth in offensive rebound percentage). He also ranks among the league leaders in field goals (12th), field goal attempts (19th), total rebounds (8th), points (20th), rebounds per game (10th), PER (17th) and total rebound percentage (15th). Zach is clearly an asset on the offensive side of the floor, although it should be noted that he has ranked among the league’s worst outlet passers when it comes to igniting the fast break.
Zach’s liabilities are exposed on the defensive end of the floor. This season, the Grizzlies have allowed opponents to score 1.5 more points when Randolph is on the floor than when he sits. In addition, he doesn’t really do anything exceptionally on the defensive end. He doesn’t steal the ball (0.7 steals per game, career), he doesn’t block shots (0.3 blocks per game, career) and he doesn’t draw many charges (0.05 charge rate; for reference Steve Nashhas a charge rate of 0.50). One of his positives on the defensive end of the floor is that Z-Bo rarely fouls (2.4 per game over his career). It is clear that Memphis did not bring Randolph in to be a defensive game-changer.
This season, there have been some noticeable changes to Randolph’s game. His usage has dropped considerably from his career average of 28.1 percent to 23.7 percent this season, which represents his lowest usage since 2002-03. Most surprisingly, he has accepted this lower usage rate gracefully which has no doubt contributed to better team chemistry on and off the court. His shot selection has also experienced minor changes; most notably he has cut down on three point attempts (down to 0.2 per game this season from 1.9 last season) with positive effects on his field goal percentage.
It is also interesting to note that his field goal percentage is over .500 on the season for the first time since 2002-03, the same season in which he saw his lowest usage percentage. This combination of lower usage and less three point attempts has allowed Randolph to score more efficiently this season, which is always a good thing. These two trends can most likely be attributed to the influence of Coach Lionel Hollins as it is doubtful that Zach would make these changes on his own. The result has been a net positive for Zach and the young Grizz squad.
But what about team success? We’ve always known Randolph could ‘get his’ but is it leading to more wins this season?
To evaluate team success, Dean Oliver provided us with a simple and powerful means of breaking down offensive and defensive efficiency numbers in his seminal book on advanced basketball statistics, Basketball on Paper. If you haven’t read Dean’s book, I highly recommend it, as he is largely responsible for kicking advanced basketball metrics into high gear. The Four Factors Oliver came up with to explain team success (or lack thereof) can loosely be thought of as shooting (eFG%), turnovers (TOV%), rebounding (ORB%) and free throws (FT/FGA). Oliver used these simple categories to analyze teams on both the offensive and defensive end of the floor.
Let’s examine Memphis’ Offensive Four Factors from last season and compare them to this season.
On offense, it appears that Randolph did help make the Grizzlies better. In particular his .505 effective field goal percentage (on 15.1 attempts) has helped provide modest increases in Memphis’ team effective field goal percentage. Z-Bo has had the biggest effect on the offensive glass, as we would expect from his league leading numbers in offensive rebounding. However, Memphis leaping to the number one spot in the league from 20th overall last season is what is really impressive. Obviously, Randolph is not solely responsible for the increase (Marc Gasol?) but he is no doubt a key player in these two improvements to the Grizzlies’ offensive efficiency.
Thus, the argument that Randolph has helped the Grizzlies on the offensive end appears to be backed up by the offensive efficiency numbers. Now take a look at the Defensive Four Factors for Memphis.
2009-10 Defensive Four Factors
eFG%: .531 (29th, same)
TOV%: .129 (24th, MUCH WORSE)
ORB%: .267 (13th, same)
FT/FGA: .201 (5th, MUCH BETTER)
On the defensive end, it is more of a mixed bag for the Grizz. On the positive side, Memphis has been better about not fouling on defense. As mentioned earlier, Randolph does not foul very much, which has had a positive effect on the team as a whole. He is most likely only partly responsible for this improvement but you can probably also credit the progression of the young Grizzlies players in general. Learning how to play defense in the NBA without fouling takes experience; simple as that. They area in which the Grizzlies regressed defensively this season is in forcing turnovers, something which Randolph does not do very well at all. Randolph is most likely partly culpable as he doesn’t steal the ball, take charges or force defenders into making bad passes.
Some concluding thoughts.
It appears that this season, Z-Bo’s personal success is finally starting to translate into more team wins. Randolph’s skills fill a need for the Grizz; they needed a guy that can create his own shot and clean up the offensive glass. In the end, it appears that the gains on the offensive ends have outweighed the losses on the defensive end. With Gasol and Randolph beasting it for the young Grizzlies squad, maybe Grizzlies general manager Chris Wallace might be a bit savvier than most people have given him credit for?
