Effects of No Rest between Games on NBA Players

There may not be NBA season but with a possibility of more packed schedule than usual due to the lockout
I wondered what are the effects of no rest between games and how important are those days providing a break. There are studies available about this issue on a team level but I haven’t seen one on a individual level.

So I’ve collected Yahoo’s split statistics for 953 player-seasons [those who played at least 41 total games in the last three years] and divided them into 5 groups based on a different situation:
“Total for a season”, “0 Days Rest”, “1 Day Rest”, “2 Days Rest”, and “3+ Days Rest”.

Here are basic averages of those groups:
[where WS/36 = Win Score per 36 minutes and GS/36 = Game Score per 36. Also please note that shooting percentages where calculated on a league level so FG% = "sum of all avg fgm" / "sum of all avg fga"]:

Situation GP Min/g FG% 3P% FT% Reb/g As/g Stl/g TO/g BL/g Fls/g Pts/g WS/36 GS/36
Season 68,7 24,73 46,04 36,19 76,79 4,22 2,20 0,75 1,39 0,49 2,11 10,33 6,32 10,81
0 days
of rest
15,7 25,18 45,86 36,58 76,91 4,24 2,17 0,73 1,40 0,49 2,17 10,43 6,11 10,58
1 day
of rest
34,0 25,12 46,02 35,94 76,88 4,30 2,25 0,78 1,41 0,50 2,13 10,47 6,37 10,85
2 days
of rest
10,8 24,67 46,37 36,54 76,81 4,21 2,23 0,75 1,39 0,49 2,10 10,38 6,34 10,85
3 days
of rest
8,2 23,01 46,08 36,26 75,68 3,99 2,08 0,73 1,32 0,49 2,02 9,73 6,31 10,82

4-5% loss maybe isn’t much of a difference but back-to-backs are indeed the worst and 1-to-2 days of rest seems the best time to play. On average that’s because of fouls, steals, rebounds, blocks, assists and FG%.

It pretty much confirms basic principles from a team level to an individual level so I’d like to dig in a little deeper.

For example, which group of players is affected the most by lack of rest? Those old veterans, right?
(Data about player’s age during each season was taken from http://www.basketball-reference.com,
“#” means “number of players in this range”)
