The best part of that post is the serious comment that some reader left. Yard-Work is hilarious.

Don't forget the season of '69 when gravity was lessened to that of the Moon's in honor of NASA's accomplishments. I'm not sure we can ever take that season's numbers seriously.

And some people refer to sabermetricians as geeks! This is taking the word geek to a whole new level. I'd like to see how Murray Chass responds to this article. Anyone dare me to forward the article to him?

Do not forget global warming, balls travel faster and farther in warmer weather.

Unfortunately, he has a good point, indirectly. Knowing where the ball lands and what the outcome is is simply inadequate as a defensive metric. How quickly a GB goes through the IF to the OF is important, as is the hang time on a FB.
Not to mention that FB hit 30 ft off the wall in Fenway are not catchable. So until you guys do a better job with the 3rd dimension (altitude) exceeding just a LD, GB. FB classification and cover the 4th dimension (time, hence velocity) better than just LD and FB classification, your results while interesting and of some use given the lack of anything better, have a lot of room for improvement.

We also would love to see home and away splits for those who play in extreme parks like Fenway and Coors, and those who play on high grass or fast turf at home.

From the Web site, for those (like me) who don't know the article isn't really by Adair: "Yard-Work.org is a work of satire and parody intended for the entertainment of our reading audience."
