I'm sure if I looked into it, I could find as many samples to disprove this as you could to prove it.
I also think anything a player did 9 years ago is not relevant today. Players just don't maintain the same physical skills at the same level over that time. To me, you can't tell me on one hand a player needs to "make adjustments" to survive in this league, and then hold him accountable for his pre-adjustment stats as if they can be used to predict what he will do tomorrow.
For any stats, I find anything older than 3 years old is probably obsolete by now. And in the post-season, it just isn't fair to take data points from a widespread number of years, when the player was in varying stages of development and adjustment, and very likely in different physical and/or health conditions, and then lump them all together and say it paints an accurate picture...
