In 2002, David played in 3 of the 5 games it took LA to beat the Spurs. In the 2 games he missed, SA started Duncan and Malik Rose in the frontcourt and Shaq scored 19 and 23 points.
In addition, during these spurs/lakers years Robinson was way past his prime and Duncan had surpassed him as an offensive and defensive player since 1999. Duncan is capable of doing at least as good a job as Robinson did, and often took responsibility guarding Shaq anyway despite David's presence.
During that series, Kobe "ballhogged" to the tune of 21 shots per game.
Conversely, vs Detroit that same year in the series that became universally known as the "Kobe Ballhog" finals, Kobe shot 22 shots per game, one more than in the SA series, and Shaq still averaged 26ppg - 4 more than in the series vs San Antonio.
The previous year vs San Antonio, Kobe shot the ball 26 times per game (5 more shots than in 2004) and Shaq still averaged 25ppg, 3 more than the 2004 series.
What we can infer from this is that, generally, there is little to no correlation of the # of shots Kobe Bryant took to Shaq's scoring average in any given series, and that his performances were primarily determined by how he himself played and how the defense strategized against him. And in this, San Antonio always managed to make his scoring manageable whether their primary defender was Tim Duncan, David Robinson, Rasho Nesterovic, or Malik Rose. Pairing Antonio McDyess with Tim Duncan would not serve to alter that substantially at all. History shows that no matter who SA had in their frontcourt, Shaq was not overwhelmingly dominant against them, if at all.
24ppg from Shaq opposed to 21ppg and DPOY defense from Duncan is not a large difference, and it is a deal that San Antonio will take. The rest of the Spurs team will outplay the rest of the Cavs team by a much more significant margin and, like I said, Shaq and Duncan will effectively neutralize each others contributions. Thus it becomes Lebron, Williams, etc. vs. 5 all-star caliber players. Like the Cavs vs Orlando series this spring but magnifiedx5.
And in the early 2000's David Robinson was not David Robinson as you're thinking of him defensively either. He was a s of his former self on both ends of the court, and not far beyond (if at all) a peak McDyess at all.
You're comparing two regular season games of Williams vs Parker to 5 years of extended playoff series' between Shaq and Tim Duncan?
Lets try to stay reasonable.
