Statistics! If you aren't into stats, you can probably skip this. I suppose I'm probably the last person on this board to discover this, but I just found www.82games.com, which has a ton of free up to date player and team stats. I can definitely see how people can get sucked into this.

Anyway, they have a nifty chart of the plus/minus for every five-man combination that the Suns have played this year. Throwing out combos that have played for less than 10 minutes total for the year so far, Coach D has used 8 combinations, for this many minutes, with this net plus/minus for each group:

1 Nash-Bell-Hill-Marion-Diaw | 66min | +21
2 Nash-Barbosa-Hill-Marion-Stoudemire | 49 min | +31
3 Nash-Bell-Hill-Marion-Stoudemire | 48 | +7
4 Nash-Barbosa-Hill-Marion-Diaw |38 | +30
5 Nash-Barbosa-Bell-Marion-Diaw | 37 | -3
6 Barbosa-Bell-Hill-Marion-Diaw | 16 | +4
7 Nash-Barbosa-Hill-Diaw-Stoudemire |13 | -2
8 Banks-Barbosa-Hill-Diaw-Stoudemire | 12 | +9

As you can see, combos 1, 2, and 4 are far and away the most successful. It's hard to spot any clear conclusions, but a few tentative observations:

(i) The "natural" starting linup (combo 3) is net positive, but is not nearly as strong as the variations. Switching Diaw in for Amare yields improvement; switching Barbosa in for Bell yields improvement, and switching both together yields improvement. The bottom line is that the team does not play as well (in terms of plus/minus) when both Bell and Amare play together, but then Bell and Amare have been injured, so I guess that isn't too surprising. I'll be curious to see if that's still true after another two dozen games.

Looking at some of the underlying stats, the "natural" starting lineup is a stronger defensive and rebounding group than the variations (no surprise because Bell and Amare are stronger defenders than LB and Diaw). Weirdly, the only stat category where they do clearly worse than the variations -- and so presumably the reason the variations do better overall -- is in percentage of "close" shots. LB clearly gets more "close" shots than Bell, but I can't think of any reason why Diaw would cause more "close" shots than Amare, unless perhaps he's better at setting up other players than Amare. Or it could be a fluke that will disappear as more games are played.

(ii) For all of the talk of Boris not playing well with Amare, it's interesting to note that Coach D has barely played them together this year. Had I copied over the rest of the chart, it would show a grand total of just 52 minutes with Diaw and Amare together in 10 games. No wonder they aren't yet on the same page. And for that matter, the team does decent (in terms of plus minus) with them together anyway. That could be a statistical mirage, but it could also be that our eyes are deceiving us a bit. It looks like Boris shrinks when Amare plays, but it's possible that there's something about him being on the floor that helps the team when Amare plays. Maybe he creates matchup problems for opposing teams that Amare exploits? (For example, teams have to play a taller player on Diaw, which creates a better match up for Amare? I don't know, just wild speculation here. . . .)

(iii) The real plus-minus poison for the team is Skinner. That's probably not really fair, since he typically plays with the second team, and only plays games against teams with big inside players where the Suns don't match up well anyway. Still, even comparing Skinner with the rest of the bench, he's far and away the worst plus-minus both on offense and defense. That doesn't mean Skinner isn't the best 8th-man option we have, but -- if the numbers stay true over the season -- it does suggest that there is a cost to playing him. (Or, if you like Skinner, maybe it means he should get more playing time to integrate better into the team. You can use statistics to prove anything :))

(iv) In terms of other individual plus-minus (per 48 minutes) among the top seven, Amare is the best at +12.6, followed by Nash and Hill at around + 10.8, then LB, Marion, and Diaw in that order, with Bell bringing up the rear at just +0.6. I guess none of that surprises me. Marion's will be little lower because he tends to play a lot of minutes with both first and second teams, as does Diaw. Nash and Amare *are* the first team. The truth is, I'm not sure you can learn that much from individual plus-minus scores on a D'Antoni team simply because so many players play so many minutes. There aren't enough "out of game" minutes to draw any firm conclusions. Still, it'll be interesting to see how some of these stats evolve as the team moves into the heart of their schedule.

Small samples when combined with recoveries from injuries and a radical change in productivity over the last four games over the first 6 makes me uncomfortable with any conclusion.

1. Bell has not been healthy.

2. Stoudemire has not been healthy.

3. Skinner had almost no training camp due to injuries.

4. Nash had shoulder issues in the past few games.

5. Hill has not in condition the first six games

Small samples can really distort any conclusions.

Actually, I agree with you, but like I said, I just found the site and couldn't help myself. In a way, it's sort of interesting to see the injuries reflected in the stats to a degree, since it's a sort of validation. On the other hand, since an injury could happen at any moment, I'm not sure you can ever really use stats about the past to say anything about the future. Still, it'll be fun (for me, at least) to see how these numbers settle in over time. Gives me something to do between games.

I'm not opposed to this kind of analysis, I just think it makes sense to get a bit further in where the sample size is not so easily distorted by just a couple of games.

The issue of Amare playing with Boris is going to be an ongoing story. So far, the evidence suggests that Boris is light years better when he's not playing with Amare.

What I can conclude from this is Hill is a great addition to the lineup and Diaw needs to get some nuts!

First of all, I can greatly admire and appreciate the time and effort you put into researching these stats. Very interesting stuff, and it certainly has value. The biggest omission I see in your research, however, is the lack of taking into account the strength of the line-ups each combination is facing. Obviously something like that would be incredibly difficult to track post-game, but it would greatly compliment and lend more creedence to your research as to which combination we have is the most effective.

If anything, your research implies that we have a deep team, and that we can be effective with a variety of combinations, even without Nash (6 & 8). It's hard to make that conclusion though, without strength of opponent taken into account.

Again, :notworthy on the research. It's a refreshing change of pace from the "trade Marion" "Amare's knees suck" "Fire D'Antoni" type threads that seem to dominate this board these days.

Let wait for 10 more games before to start a deeper analysis.
But your first impression are interesting.

As azirish says we can't conclude much for a bunch of player. I hope our natural lineup +/- will be way better as the season goes on.

Still you made a couple of interesting observations.

Here are mine:
- Diaw being effective when he plays C with Amare out his not a surprise. Diaw is a matchup nightmare at C. When Amare is out he touches the ball enough to be effective in his own way. Maybe the little surprise is that Diaw playing C doesn't hurt our defense.
I hope Boris will find a way to be effective when Amare is in, but I am not sure he can.
- Marion is a PF not a SF (once again not a big surprise)

In a van...down by the river.
Nice work stargazer. I get into stats also.
There's a statistic that i've been curious about since America West Arena/US Airways opened 15 years ago.
I would like to compile the average FG% of all VISITING teams to our building since it opened....and then do the same for all the other arenas in the league(visitors FG%) over the same 15 years, and look at which buildings were the toughest,and easiest to shoot in.
I have a feeling that the visiting team's FG% shot in the Purple Palace is very high & near the top because i swear that that building brings the best out of shooters & non-shooters everywhere.

Funny is however that Amare doesn't touch the ball very often anyway with or without Diaw. I guess his additional effectiveness is due to Nash resting rather than Amare demanding the ball too much.

I'm starting to think that it's not quite as simple as Boris and Amare not being able to mesh together. I think they work much better together when Nash is not on the floor, and Boris is the primary ball handler at the elbow. Amare and Boris have played the two-man game relatively effectively in those situations - they even hooked up for that Boris-to-screener alley-oop in the Houston game.

It makes sense - Boris is much more comfortable with the ball in his hands, and Nash does dominate the ball somewhat. Granted, it is definitely a small sample size, but check out the last lineup in the list - it's Diaw and Stoudemire with (gasp!) Banks at the point.

He doesn't have to, he just have to be the #1 inside option (thanks god he is).

Nash-Bell-Hill-Marion-Diaw | 66min | +21
Nash-Barbosa-Hill-Marion-Diaw |38 | +30
(+ 2005-2006 season)

Nash/Diaw cohabitation doesn't look like a problem if Amare is out.

And it is not
Amare demanding the ball too much.
But "Diaw not able to adapt to a different role when Amare is in"
