Hi Everyone,
I'm trying to incorporate home-court advantage into my dissertation proposal, but I'm having trouble finding what I expected to be some fairly common statistics. The first is a break-down of each team's average age and experience for rotation players. That is, of the 8 or 9 guys who average more than 10 minutes a game, how long have they been in the league and how old are they? I thought this would be useful for analyzing the benefits of experience, but it doesn't seem like anything anyone has done. Has anyone ever come across this?
Likewise, I'm trying to find a breakdown of within-division, within-conference, and outside-conference won/loss records that takes into account home vs. away games. They are usually treated separately, but I just want to know how teams do home vs. away against their divisional opponents (those tough rivalry games).
If anyone can point me in the right direction, I would really appreciate it. If it doesn't exist, I'll compile it by hand myself and try to get it in an accessible spot.
Thanks for your help, everyone.

Hi, welcome.
Guide to 20 some versions of standings on the web

You will probably have to compute average age and experience for your rotation cutoff level yourself.
Let us know more about the dissertation if you wish. |

Thanks, Mountain, but none of those really has what I'm looking for.
What I'm trying to do is determine why teams play better at home than on the road. I've been using home winning % - away winning % as "home court advantage" and trying to correlate this new variable to other team characteristics. For example it doesn't correlate at all with how full the arena is, on average, over the course of an entire season. Teams like Detroit, Boston, and Philadelphia have been getting far less of an advantage over the past four years compared to teams such as Golden State, Milwaukee, and the LA Clippers. My next two goals are to determine whether more experienced teams play better on the road, and to determine whether playing out of one's conference on the road is a bigger challenge than playing within one's conference on the road. To figure out the last one, I need to know each teams divisional record at home vs. on the road, their conference record at home vs. on the road, and their out of conference record at home vs. on the road. Sadly, nobody bothers to break it down this way because it says less about the individual teams and more about the sport itself. |

I suspected that you would have to compile the home-away team record splits down to division and conference levels yourself but thought it was worth mentioning the list in case any of them went further than normal or to confirm that no such source exists so you could resign yourself to the manual compiliation.
Thanks for the thumbnail description of your approach.
Let us know how it turns out.

Doug has home/away splits at the team and player level going back many seasons.

Thanks for the advice. I'm going to go ahead and compile it, and I'll try to post it somewhere when I'm done. |

That may be the best metric, but you may find that this differential is roughly proportional to a team's overall winning%. That is, if a .500 team is usually .560 at home, a .650 team may be .730 at home (rather than .710). You should check to see if there's a correlation btwn the spread and win%, and if so, then adjust accordingly.
And if you haven't already, you may want to examine the year-to-correlation of your home-field metric, to see how much real home field "skill" teams have. A significant correlation means teams really have some tendency to over/under-perform the average HF advantage. Alternatively, you could find that the correlation is so low that there's really not much to study here. |

Antecrash the home-road splits you seek are compiled at the excellent hoopsstats.com.
Use this home page http://www.hoopsstats.com/basketball/fantasy/nba/standings/08/4
for conference and divison records at home and the corresponding road page.
It was on the list I gave you but this breakout might not have been obvious as there are many pages and drop down menus. Data for past 10 years and current season. |
