"Different stats have different aging curves"

Post by aliebling »

According to Kevin Pelton (http://basketballprospectus.com/unfiltered/?p=399), we know that different stats have different aging curves (something that makes intuitive sense).

Does anyone have aging curves for the primary stats that they can share or know of a good source for same? I'm really trying to avoid having to go and compile this datya myself. :D

at http://www.bballsports.com, you can download for free the superdb.exe (historical stats for the four major sports), open the basketball players database, and subtotal (like in a spreadsheet) the player stats by age to see how each stat (per game, per minute, per touch) change between the ages of the late teens to 40+...

you can even first limit it to all players who played in the league up and through a specific age, and then subtotal it by age so you are looking at a select group of players who played at each age group (or close to it)...

I think Ed Kupfer posted some work on that a while back. It may have been lost when the forum was hacked.

A quick search of the board yielded this topic that Crow very generously saved (Thank you Crow!):

Hope that's kinda what you're looking for.

GD: I am muchly impressed by your search-fu. Every time I try to search for anything on this site, it seems to tell me all my search terms are too common and will be ignored (when searching for "aging curve" for example).

In any case, this is exactly the sort of data I was looking for! Is Ed still around or does anyone have his data?

Actually, I just randomly clicked on the last page of the forum and that topic happened to be there. But I'm glad it could help!

As far as I know, Ed still posts here. Last I heard he was working for the Rockets, though, so I don't know if he's able to share any of his data.

Thanks for saying thanks G.D. and more importantly for helping someone else, namely aliebling.

I see that in the thread by Ed you linked to that I didn't recover absolutely all the charts at the end. I don't know if I missed them or if they weren't available in my earlier efforts but they are gone from my recovery reach now.


I'll again link to several ways to search given that the site's search tool is useless at least for keyword search and there appears to be no hope of remedy. Options, if you want to try them. May not be as convenient as desired or always successful but they can find a lot with a bit of patience and effort.

By google:

(or by manual search of the forum pages, or search using the site search by a thread author or participant's screen name)



Or by using this index of thread topics to get a sense of where to find the thread:
