Michael Lewis (Moneyball) calls Shane Battier the no-stats all-star:

It was, and is, far easier to spot what Battier doesn’t do than what he does. His conventional statistics are unremarkable: he doesn’t score many points, snag many rebounds, block many shots, steal many balls or dish out many assists. On top of that, it is easy to see what he can never do: what points he scores tend to come from jump shots taken immediately after receiving a pass. “That’s the telltale sign of someone who can’t ramp up his offense,” Morey says. “Because you can guard that shot with one player. And until you can’t guard someone with one player, you really haven’t created an offensive situation. Shane can’t create an offensive situation. He needs to be open.” For fun, Morey shows me video of a few rare instances of Battier scoring when he hasn’t ­exactly been open. Some large percentage of them came when he was being guarded by an inferior defender — whereupon Battier backed him down and tossed in a left jump-hook. “This is probably, to be honest with you, his only offensive move,” Morey says. “But look, see how he pump fakes.” Battier indeed pump faked, several times, before he shot over a defender. “He does that because he’s worried about his shot being blocked.” Battier’s weaknesses arise from physical limitations. Or, as Morey puts it, “He can’t dribble, he’s slow and hasn’t got much body control.”

Battier’s game is a weird combination of obvious weaknesses and nearly invisible strengths. When he is on the court, his teammates get better, often a lot better, and his opponents get worse — often a lot worse. He may not grab huge numbers of rebounds, but he has an uncanny ability to improve his teammates’ rebounding. He doesn’t shoot much, but when he does, he takes only the most efficient shots. He also has a knack for getting the ball to teammates who are in a position to do the same, and he commits few turnovers. On defense, although he routinely guards the N.B.A.’s most prolific scorers, he significantly reduces their shooting percentages. At the same time he somehow improves the defensive efficiency of his teammates — probably, Morey surmises, by helping them out in all sorts of subtle ways. “I call him Lego,” Morey says. “When he’s on the court, all the pieces start to fit together. And everything that leads to winning that you can get to through intellect instead of innate ability, Shane excels in. I’ll bet he’s in the hundredth percentile of every category.”

There are other things Morey has noticed too, but declines to discuss as there is right now in pro basketball real value to new information, and the Rockets feel they have some. What he will say, however, is that the big challenge on any basketball court is to measure the right things. The five players on any basketball team are far more than the sum of their parts; the Rockets devote a lot of energy to untangling subtle interactions among the team’s elements. To get at this they need something that basketball hasn’t historically supplied: meaningful statistics. For most of its history basketball has measured not so much what is important as what is easy to measure — points, rebounds, assists, steals, blocked shots — and these measurements have warped perceptions of the game. (“Someone created the box score,” Morey says, “and he should be shot.”) How many points a player scores, for example, is no true indication of how much he has helped his team. Another example: if you want to know a player’s value as a rebounder, you need to know not whether he got a rebound but the likelihood of the team getting the rebound when a missed shot enters that player’s zone.

There is a tension, peculiar to basketball, between the interests of the team and the interests of the individual. The game continually tempts the people who play it to do things that are not in the interest of the group. On the baseball field, it would be hard for a player to sacrifice his team’s interest for his own. Baseball is an individual sport masquerading as a team one: by doing what’s best for himself, the player nearly always also does what is best for his team. “There is no way to selfishly get across home plate,” as Morey puts it. “If instead of there being a lineup, I could muscle my way to the plate and hit every single time and damage the efficiency of the team — that would be the analogy. Manny Ramirez can’t take at-bats away from David Ortiz. We had a point guard in Boston who refused to pass the ball to a certain guy.” In football the coach has so much control over who gets the ball that selfishness winds up being self-defeating. The players most famous for being selfish — the Dallas Cowboys’ wide receiver Terrell Owens, for instance — are usually not so much selfish as attention seeking. Their sins tend to occur off the field.

It is in basketball where the problems are most likely to be in the game — where the player, in his play, faces choices between maximizing his own perceived self-interest and winning. The choices are sufficiently complex that there is a fair chance he doesn’t fully grasp that he is making them.

Taking a bad shot when you don’t need to is only the most obvious example. A point guard might selfishly give up an open shot for an assist. You can see it happen every night, when he’s racing down court for an open layup, and instead of taking it, he passes it back to a trailing teammate. The teammate usually finishes with some sensational dunk, but the likelihood of scoring nevertheless declined. “The marginal assist is worth more money to the point guard than the marginal point,” Morey says. Blocked shots — they look great, but unless you secure the ball afterward, you haven’t helped your team all that much. Players love the spectacle of a ball being swatted into the fifth row, and it becomes a matter of personal indifference that the other team still gets the ball back. Dikembe Mutombo, Houston’s 42-year-old backup center, famous for blocking shots, “has always been the best in the league in the recovery of the ball after his block,” says Morey, as he begins to make a case for Mutombo’s unselfishness before he stops and laughs. “But even to Dikembe there’s a selfish component. He made his name by doing the finger wag.” The finger wag: Mutombo swats the ball, grabs it, holds it against his hip and wags his finger at the opponent. Not in my house! “And if he doesn’t catch the ball,” Morey says, “he can’t do the finger wag. And he loves the finger wag.” His team of course would be better off if Mutombo didn’t hold onto the ball long enough to do his finger wag. “We’ve had to yell at him: start the break, start the break — then do your finger wag!”

Hockey has used a plus-minus stat for years. Now basketball is catching on:

One well-known statistic the Rockets’ front office pays attention to is plus-minus, which simply measures what happens to the score when any given player is on the court. In its crude form, plus-minus is hardly perfect: a player who finds himself on the same team with the world’s four best basketball players, and who plays only when they do, will have a plus-minus that looks pretty good, even if it says little about his play. Morey says that he and his staff can adjust for these potential distortions — though he is coy about how they do it — and render plus-minus a useful measure of a player’s effect on a basketball game. A good player might be a plus 3 — that is, his team averages 3 points more per game than its opponent when he is on the floor. In his best season, the superstar point guard Steve Nash was a plus 14.5. At the time of the Lakers game, Battier was a plus 10, which put him in the company of Dwight Howard and Kevin Garnett, both perennial All-Stars. For his career he’s a plus 6. “Plus 6 is enormous,” Morey says. “It’s the difference between 41 wins and 60 wins.” He names a few other players who were a plus 6 last season: Vince Carter, Carmelo Anthony, Tracy McGrady.

Battier’s strengths are subtle:

Before the Rockets traded for Battier, the front-office analysts obviously studied his value. They knew all sorts of details about his efficiency and his ability to reduce the efficiency of his opponents. They knew, for example, that stars guarded by Battier suddenly lose their shooting touch. What they didn’t know was why. Morey recognized Battier’s effects, but he didn’t know how he achieved them. Two hundred or so basketball games later, he’s the world’s expert on the subject — which he was studying all over again tonight. He pointed out how, instead of grabbing uncertainly for a rebound, for instance, Battier would tip the ball more certainly to a teammate. Guarding a lesser rebounder, Battier would, when the ball was in the air, leave his own man and block out the other team’s best rebounder. “Watch him,” a Houston front-office analyst told me before the game. “When the shot goes up, he’ll go sit on Gasol’s knee.” (Pau Gasol often plays center for the Lakers.) On defense, it was as if Battier had set out to maximize the misery Bryant experiences shooting a basketball, without having his presence recorded in any box score. He blocked the ball when Bryant was taking it from his waist to his chin, for instance, rather than when it was far higher and Bryant was in the act of shooting. “When you watch him,” Morey says, “you see that his whole thing is to stay in front of guys and try to block the player’s vision when he shoots. We didn’t even notice what he was doing until he got here. I wish we could say we did, but we didn’t.”

People often say that Kobe Bryant has no weaknesses to his game, but that’s not really true. Before the game, Battier was given his special package of information. “He’s the only player we give it to,” Morey says. “We can give him this fire hose of data and let him sift. Most players are like golfers. You don’t want them swinging while they’re thinking.” The data essentially broke down the floor into many discrete zones and calculated the odds of Bryant making shots from different places on the court, under different degrees of defensive pressure, in different relationships to other players — how well he scored off screens, off pick-and-rolls, off catch-and-shoots and so on. Battier learns a lot from studying the data on the superstars he is usually assigned to guard.
