It’s baseball season and, like every year, some teams are now on winning streaks, some on losing streaks.

Soon we’ll know which teams will collapse, which ones will suddenly get it together. It can’t just be a matter of talent.

Some teams, no matter the sport, seem to fall into a losing habit, while others have a winning attitude.. Some teams choke, those that win Super Bowls do not.

What’s the difference between them? That’s a question for coaches but also for sports psychologists. More teams are hiring them.

This hour On Point: the intangible factor in team performance.

“There’s No I in Team”

After concluding that defense doesn’t necessarily win champion-ships, we decided to examine another shopworn bit of sports wisdom. Before young athletes are capable of lacing their sneakers and putting on their cleats, they’re invariably taught, “There’s no I in team.” This spelling lesson is, of course, meant to reinforce the virtues of teamwork, stressing the importance of unity and the corrosive effects of attempts at personal glory. But does it accurately capture reality?

It’s in basketball that the no-I-in-team cliché is most often tossed around. If we were to compile a list of the top, say, fi ve or six NBA players over the last 20 years, it probably would include Michael Jordan, Kobe Bryant, Tim Duncan, Shaquille O’Neal, Hakeem Olajuwon, and LeBron James. If there were no I in team, those stars wouldn’t much matter. A team that formed a symphonic whole, with five players suppressing and sublimating ego for a common goal, could surmount teams with the “I” players, stars willing and able to play selfishly when the situation calls for it. But that’s rarely the case. Since 1991, every year at least one of those players has appeared in the NBA finals. Go back another decade and add Larry Bird and Magic Johnson and now at least one of the top eight players has been featured in all but one NBA finals series for the last 30 years. In other words, a remarkably small number of select players have led their teams to the vast majority of NBA titles. Lacking one of the best players in history has all but precluded a team from winning.

We wondered how likely it is that an NBA team without a superstar wins a championship, makes it to the finals, or even makes it to the playoffs. We can define superstars in various ways, such as first-team all-stars, top five MVP vote-getters, or even those with the top five salaries. Pick your definition; it doesn’t much matter. The chart below shows what we found for the NBA.

A team with no starting all-star on the roster has virtually no chance—precisely, it’s 0.9 percent—of winning the NBA champion-ship. More than 85 percent of NBA finals involve a superstar player and more than 90 percent of NBA titles belong to a team with a superstar. The graph also shows, not surprisingly, that as a team gains superstars, its chances of winning a title improve dramatically. One first-team all-star on the roster yields a 7.1 per-cent chance of winning a championship and a 16 percent chance of making it to the finals. A team fortunate enough to have two first-team all-star players stands a 25 percent chance of winning a championship and a 37 percent chance of making the finals. On the rare occasions when a team was somehow able to attract three first-team all-stars, it won a championship 39 percent of the time and made the finals 77 percent of the time.

The numbers are even more striking when we consider the top five MVP vote recipients. A team with one of those players stands a 15 percent chance of winning it all and a 31 percent chance of making the finals. Having two of those players yields a 48 percent chance of winning the championship and a 70 percent chance of making the finals.

Really, it’s no mystery why the Miami Heat fans celebrated deliriously when the team lured LeBron James in the summer of 2010. When James “took his talents to South Beach” and joined Dwyane Wade and Chris Bosh, it made the Heat a virtual lock to go deep into the playoffs. Having the MVP (James) in addition to two other all-stars makes the Heat 98 percent likely to make the playoffs, 70 percent likely to make the finals, and 36 percent likely to win it all.

At some level this stands to reason, right? The superstars are usually going to be concentrated on the best basketball teams. The average winning percentage of teams with a first-team all-star on their roster is 56 percent. Two first-teamers and it’s 63 percent. Have a top-five MVP vote-getter and your team wins 64 percent of its games; that in itself calls the “no-I-in-team” shibboleth into question.

Here’s where it gets interesting. Even after controlling for the team’s winning percentage during the regular season, teams with superstars do measurably better in the playoffs. That is, a top-five MVP candidate improves his team’s chances of winning a championship by 12 percent and of getting to the finals by 23 percent even after accounting for the regular season success of the team. This implies that superstars are particularly valuable during the playoffs—ironically, the time when “team” is relentlessly stressed by coaches, media, and analysts.

What about the notion that a lineup of five solid players is bet-ter than a starting five of one superstar and four serviceable sup-porting role players? One way to test this idea is to look at the disparity among a team’s starters in terms of talent. Controlling for the same level of ability, do basketball teams with more evenly distributed talent fare better than teams with more dispersed talent? Measuring talent is difficult, but one reasonable metric is salary. Controlling for the average salary and winning percentage of teams, do teams with bigger differences in salaries among their starting players fare worse than teams whose salaries are spread more evenly among the players?

We find the opposite, in fact. Teams with more variable talent across their players are more likely to make the finals and more likely to win a championship than teams with more uniformly distributed talent. Again, this suggests that a superstar with a relatively weak supporting cast fares better than the team with five good players.

The same holds for the NHL and even soccer. Without a prolific goal scorer and/or goaltender/goalkeeper, survival in the postseason tends to be short-lived. There may be an I in Major League Baseball, too, but the effects are considerably weaker, in part because the team is larger, making it harder for one player to change the overall make-up of the team. Nonetheless, the bulk of World Series titles and appearances belong to the teams with a handful of elite superstars, both hitters and pitchers. But there are some examples of championship teams without a starting all-star player. (Name a “star” on the 2003 Florida Marlins. How about the 2002 Angels?) But this makes sense. Although we focus on individual achievements in baseball, it’s hard for any one player other than the starting pitcher, who pitches only one game out of five, to take control of a game. Even the best hitters come to bat only once every nine times.

If the evidence suggests that in basketball, hockey, and soccer a handful of individual players are extremely valuable for success, why do so many coaches and commentators place such heavy emphasis on the team? Perhaps it’s because admitting that in these sports the star matters as much as he does blunts the incentive for the rest of the team. Though teammates may be less valuable than the stars, they still have some value. They’re needed to grab rebounds, pass, block, chase loose balls, and defend. Sure, the superstar makes a big difference, but he can’t do it alone. In that sense, the team certainly does matter.

Stars tend to recognize this delicate balance. Remember how lustily Michael Jordan embraced the conventional wisdom that “defense wins championships,” a phrase that galvanized his teammates? Nonetheless even Jordan felt differently about the “no-I-in-team” truism. He recognized that not all players were created equal.

At his 2009 induction into the Basketball Hall of Fame, Jordan gave a speech that revealed much about his turbo-powered competitive drive. He told a story of once scoring 20 consecutive points late in a game to lead the Chicago Bulls to victory. Afterward, he was admonished by Tex Winter, the Bulls’ eminent longtime assistant coach, “Michael, there’s no I in team.” Jordan recalled his response: “I looked back at Tex, and said, ‘There’s an I in win. So which way do you want it?’”

    Well my Yankees are surging once again. Talk a little bit about the back and forth between us and that team in Boston whose name I will not utter. It seems as though it will be a year of 9-1 or 12-3 streaks on the plus and minus side like I can’t really recall at least in the AL East. It eventually will come down to us or The Sox against the dominance of the Phillie pitching staff right?

    • Cory

      Aah yes…  3 teams built on talent bought and paid for from other teams.  That is definitely one road to victory.

      • wauch

        Fair enough but I would ask if you would trade your team’s owner for ours? I would guess the answer would be yes immediately. Unless your a Cubs fan and you simply enjoy being a loser!

        • ThresherK

          Trade owners, or trade payrolls?

          A college FB coach was complemented by a rival with “He could take his and beat yours, and he could take yours and beat his.” Neither the Yankees or Red Sox (often first and second in MLB payroll) need to wonder about this hypothetical.

    I sort of wish you had a little league baseball coach or a high school wrestling coach on the panel today.  Focusing entirely on professional sports means focusing on money.  I think a truer test of coaching and teamwork is taking an existing team and getting the best out of them, instead of loading up on talent and trying to get them to work together.

  • Gary2

    All sports are pointless boring waste of time crap.  Please discuss something of importance…

  • Cory

    Speaking of teamwork…  the Greek citizenry continue to give their government hell over proposed austerity measures.  Seems people are hesitant to allow themselves to be screwed by the establishment.  I say, GO GREEKS GO!  GO GREEKS GO!  YAY ORDINARY PEOPLE!

  • Paul

    Some pretty fuzzy logic in this discussion of “I” teams. For instance, every team needs a draw. “I” players put bums in seats and more than pay the “I” player’s salary. If all the teams have “I” players how can you realistically compare teams. That’s just one problem I have with this theory.

    Why are there streaks in sports? Easy answer- the bell curve of probability.

    I think its important to consider the study/statistic that was done last year about NBA teams. It was found that across the board the teams who do better and are better (eg ’08 celtics) touch each other MUCH more than teams that do worse. This function of comradery just goes to show that teams are highly dependent on each other and a couple down guys can sink the ship!

      Can you share this study with me please. I am writing my dissertation on this topic pellecier@mac.com

    Based on comments from winning athletes after the game, doesn’t Jesus personally pick the winners?

    • GLH

      With 12 disciples and Himself as player/coach Jesus had enough fit young personnel to challenge the opposition in all major team sports.
      People think they went around begging but that is a misconception. Skin games and side bets (see the movie “Diggstown”) caused Jesus and entourage to live off the Phat of the land. The Sadduci bookies and Roman state betting wouldn’t tolerate these Indies, so they popped rapper Jesus like Tupac and Biggie Smalls. Before the Crucifixion this team had the longest winning streak in history. The Lord was a slam dunk homerun funk talking trash as he thunk.

    I think you are cheating about the Cubs here. Just because their games start at 2 in the afternoon does not mean they could not arrive for work at 9 or 10 am to do the rote stuff.  They go home early, they can come in early. 

  • calisgr8

    Please do not disparage my beleaguered Orioles too much. Our suffering is great, our pitching indescribable with polite words. Our eyes bleed. Yes, we are losing as I write this. Sigh.

    • calisgr8

      To answer your question, all Orioles fans have a theory about why the Os lose season after season. Personally, I blame our pitching and comfort myself with a little extra blame (for their budgets) and hate for the Yankees and Red Sox, just for good measure.
