My expectations for David West:
- To score 16-18ppg on a TS% of about 52-53% which I think will drop to about 50-51% in a playoff series against a tough defensive matchup (of which I think T.Gibson and New York qualifies)
- I also expect him to corral about 7.5-8.0 rebounds a contest in 35-38 minutes (well below average).
- I consider David West to be an average to slightly below average defender. I expect him to drop off to below average but serviceable defender. Taj Gibson is not a talented enough individual offensively to take advantage of this so this isn't a large issue in this matchup. On team defense, he'll be well protected by his teammates so the expected decline shouldn't be a large issue there either.
My evaluation of Taj Gibson
- I think Taj Gibson is a solid role player offensively who can give 10-12ppg in starters minutes on a TS% similar to David West.
- Taj Gibson is an above average rebounder who can grab 9-10 rebounds a contest in starter's minutes. Taj Gibson is also a very good shot blocker who can create turnovers and generate extra possessions for his team that way too.
- Taj Gibson is an above average defensive player who will help decrease David West's scoring efficiency + improve the Knicks team defense. That team defense, especially his pick and roll defense + transition defense + weak-side shot-blocking adds good value to the Knicks. A plus for Gibson.
So, I consider Taj Gibson to be the superior defensive player + possession creator and David West to be the superior offensive player but to score his points on a below average TS% and on a number similar (TS%) to his less talented offensive counterpart.
Given those expectations, in terms of overall contribution, I do not think David West has an advantage over Taj Gibson.
But that is just me talking and it is based on my expectations of David West suffering a decline in performance. Without that decline, this matchup is firmly in D.West's favour.
