NBA Rosters and Team Changes: 2013-2014

I have downloaded statistics for all NBA players from basketball-reference.com, and accounted for roster changes (as of Sunday, October 5).

The Tm2013 column is a three-letter abbreviation for the player’s 2013-2014 team. For players that played on two or more teams, the entry represents the team for which the player played the most minutes. The Tm2014 is the player’s current NBA team (as of Sunday, October 5) according to nba.com. Rookies are not included in this spreadsheet.

If you’ve read my previous two posts, you may have guessed that I am leading up to a prediction of the upcoming 2014-2015 NBA season. You’d be correct – I will post my model and predictions tomorrow.

In the meantime, you can actually use the spreadsheet above to create a very crude prediction. The last column in this spreadsheet is “win shares”. If you create a pivot table based on Tm2014 and Win Shares, you get the sum of player win shares for current rosters – a crude measure of team strength. Here is what that table looks like:

Team Sum of WS
CLE 60.7
SAS 59.4
TOR 58.6
LAC 58
IND 56.6
OKC 54.1
GSW 53.8
PHO 52.6
POR 50.8
DAL 48.6
HOU 47.9
WAS 46.8
NYK 44.3
DET 43.9
MEM 43.5
MIA 40.8
CHI 40.4
ATL 38.9
DEN 36.9
MIN 34.3
SAC 32.6
CHA 32.1
NOP 31
LAL 26.9
BRK 26.1
BOS 25.9
UTA 23.8
ORL 23.1
MIL 21.3
PHI 7.2

I can think of at least five weaknesses in this “pivot table model”. Can you?
