Regression's A Powerful Force

PrintNo new ideas presented here. I just remember that, back when I was first learning about regression, one of the things that stuck with me was seeing how the top batting averages in the league in Year X looked in Year X+1, so here's a similar concept with a different, more contemporary statistic. What you see below are the top 20 players in WAR in 2008 and how they then did in 2009. Accompanying them is an old friend.
Please try to keep this in mind if you notice that Franklin Gutierrez is having a tough time repeating as a superstar.

David Wright's regression came despite a .400 BABIP

David Wright missed a ton of playing time

I'm not exactly sure what you mean
He’s never had above a .400 BABIP for a season.

I get what you're saying but .400 is quite high compared to his career averages
You’re likely correct about the injuries causing his sudden and dramatic drop-off in power, though.
OK, now I've got a better idea what you meant
You’re right that a .400 BABIP isn’t really sky-high for him considering his usual high BABIP, but it is still something we should expect to regress back down next year. The other interesting thing is that his road ISO this year was only 8 points higher than his home ISO, so Citi Field didn’t really even contribute to the power loss.

It wasn't a mathematical argument that his avg wasn't going to regress
just a little context for non-Mets fans that David Wright tends to have above-average BABIPs
We were arguing?
“High” is totally subjective. Yea it’s 60 points above his career average and will probably regress. My point was that his career average was .340, which is above average to start with. Why have a pedantic debate over what is the formal definition of “high” is?
Damn you Jeff.
On the crappy connection here at work, it took that image a second to load. But once it popped up on the screen it made me recoil.
FUCK THE ANGELS! FUCK THE ANGELS! FUCK THE ANGELS!
This is fine.
However if it were sideways I wouldn’t be able to stop laughing for a good two minutes.

Why has nobody run with Next Laird? Eyebrows is hampered by his employer, but
we’ve got to be able to make something out of the combination of both photos.
His rugged good looks are also a powerful force.
And they can not be regressed….

Now I'm confused as to the definition of regression again.
Regression is not the same as decline due to aging, is it? This is a serious question, not a set up.
