Ryan Braun won the National League’s Most Valuable Player award
on Tuesday. But a lot of sports fans think Dodgers center fielder
Matt Kemp was more deserving. Kemp did have a better year. He hit
39 home runs to Braun’s 33. Kemp and Braun are both average
defensive players. But Kemp plays center field, a demanding
position usually manned by defensive specialists who can’t hit a
lick, not someone who hits .324 with power. Braun plays left field,
a far easier position where offensive production is part of the job
description. The reliable Kemp didn’t miss a game all season. Braun
missed a dozen with a bum leg, and played hurt for the better part
of a month. Was Kemp robbed?
The reason Kemp lost was that his Dodgers were a middling
team this year, finishing with an 82-79 record. Braun’s Milwaukee
Brewers won 96 games and nearly made it to the World Series. The 32
sportswriters who vote for the NL MVP β two from each NL team’s
city β have a well-known bias in favor of players from contending
teams. In essence, Kemp was punished for the sin of having less
talented teammates than Braun. How is this fair?
As it turns out, it’s perfectly fair. Kemp had the better
year, but Braun created more value β and remember, this is the Most
Valuable Player award. To find out why, you need to think at the
margin. That means thinking of how much value one more victory
would create.
We can do that with the help of a statistic some
pointy-headed number crunchers invented not too long ago. It’s
called Wins Above Replacement, or WAR. It tries to measure the
difference between a major league player and a hypothetical
replacement player brought up from the minors. With Matt Kemp in
the lineup instead of his AAA replacement, the Dodgers won 10 extra
games. Braun’s WAR was 7.7.
Again, Kemp clearly had a better 2011. But at the margin,
Braun was far more valuable. Without Kemp, the Dodgers would have
won 72 games. With him, they won 82. That’s not a big difference at
the margin. It’s nice to finish above .500, but there’s no real
difference between a 72-win season and an 82-win season. You miss
the playoffs either way.
Braun took the Brewers from 88 wins to 96 wins. There is a
world of difference between 88 wins and 96 wins. It’s the
difference between missing the playoffs and winning the division.
Every single win that Braun created was absolutely crucial to the
Brewers playing in the postseason instead of watching it from
home.
So even though Braun created fewer wins, each of them was
extremely valuable. That’s why he’s the MVP.
The MVP voters’ longstanding bias against superior players
on inferior teams can be maddening when a player has a year like
Kemp had and doesn’t win. But while I doubt any of the
sportswriters have advanced degrees in economics, they seem to
instinctively know the value of thinking at the margin.
Kemp did win a Silver Slugger award, given to the best
offensive player at each position. That’s not a bad consolation
prize. Of course, Braun won one, too.
Still, I think Kemp can have the last laugh. Earlier this
year, Braun signed a 10-year, $105 million contract extension. But
Kemp just signed a new contract himself. Between now and 2019,
Braun will earn $111.5 million in salary. Kemp will make $158
million. He may be understandably salty about not winning the MVP,
but he has some bragging rights of his own.
