The finals are usually the time when the best of the best performed the best. It is no secret that Shaq's dominance was punctuated by the monstrous numbers he posted against the 76ers, Pacers and Nets. At the same time, Duncan's numbers against the Knicks, Nets, Pistons and the Cavs solidified him as one of the greatests.
I am going to attempt to look at the numbers of Shaq and Duncan vs. the Nets in the 02 and 03 Finals, respectively.
The fantastic thing is that the two Nets teams were very similar in their approach, and this came during back to back years. Shaq and Duncan were also at the absolute peak when they faced the Nets, giving us a good look at how each of the giants performed under similar cir stances.
At first glance, people will say "what is there to compare? Duncan posted monster numbers, but Shaq's numbers were better." And this has created a common view that Shaq's peak was simply much higher than Duncan's. I am here to attempt to answer whether this is true.
Shaq averaged 36.25 PTs on 59.5% FG, grabbed 12.25 RBs, handed 3.75 asts, 2.75 blks, and had 3.5 TO per game throughout the series
While Duncan avearged 24.17 PTs on 49.5%, 17 RBs, 5.3 ASTS, 5.3 BLKs, and 3.83 TO.
The numbers are there, Shaq was better offensively, Duncan was better defensively, and numbers-wise, Shaq has the edge. But this view generally fails to account for the difference in the style of play of either teams. The Lakers were a dominant offensive and avearge defensive squad, while the Spurs were a dominant defensive and poor offensive squad. The style either team plays have a significant impact on the final statistics of either player.
Offense
Shaq averaged more than 50% PTs than Duncan did. pretty cut and dry, right? While Shaq was obviously a better on offense than Duncan, the gap was not as much as anticipated.
In 2002, the Lakers averaged 106 PPG, while the Nets averaged 96.75 PPG.
In 2003, the Spurs avearged 87.3 PPG, while the Nets averaged 82 PPG. This means that Shaq scored 34.2% of the Lakers points, while Duncan scored 27.5% of the Spurs points, additionally, if we factor in the the Net's points, Shaq scored 17.9% of the total points scored in each game, while Duncan scored 14.2%. While the difference of 3.7% was still large, the pace factor showed that Shaq was scoring only about 25% or so better than Duncan when pace is factored in.
Another element that has always been dismissed were the assists. Duncan averaged about 1.58 more asst per game than Shaq did. This translates to 3.16 pts per game when these are all two pointers. (We know for a fact that many of the two big men's assists were on 3 pters, but for argument's sake, lets all assume they are 2 pters.) When assists are factored in, we can see that Duncan was directly responsible for 39.7% of his team's offense, while Shaq was at 41.3%. While there is a difference, it is really no where close to what people perceived to be.
Defense
Duncan averaged 17 RPG, Shaq averaged 12.25, Duncan is about 40% better. That is also misleading. Keep in mind that in a faster pace of the Lakers game, there would be more rebounds. I took the total rebounds available for each game, and found that Duncan grabbed 19.2% of the available rebounds, while Shaq had 15.6%, which means that Duncan was only about 24% better rebounder instead of 40%.
In terms of blks, Duncan averaged 94% more blks than Shaq per game, but again, the more shots there are, the more blk opportunities there are. So I expressed the blks/game to the Net's total FGA per game, and found that Duncan blocked 6.5% of the Net's FGA (think about it, that means for every 15 or so shots the Net's put up, Duncan sends one back, this is pretty incredible), while Shaq blocked 3.1% of the Net's FGAs. In other words, Duncan is actually 110% better at blks when playing against the Nets in the finals.
Conclusion
In conclusion, while there is no doubt Shaq is better than Duncan offensively, the difference was really minor, in fact, Shaq was only 1.6% more responsible for the Lakers offense than Duncan was for the Spurs.
On defense (well ... reboudning and blk shots anyways), Duncan was much better than Shaq.
In conclusion, the peak of both players, while compared against similar opponents under similar cir stances during their respective primes, are about the same, pretty much debunking the myth that Shaq's peak was much higher than Duncan's.
