Vladimir Guerrero has an O-swing percentage of 46.5% (the % of pitches outside the zone that he swings at) which is highest in MLB:Griffin immediately jumped to the defense of the author, Geoff Baker. Griffin always hated Ricciards, and wasted no time attacking him on the same lines. So, yeah, that was him. Being a moron, like always. One of the idiotic things he said was that the Jays wouldn't have taken Jackie Robinson, if he were around today. BTW, Guerrero isn't a good example - by OBP standards, he's an elite player. The Moneyball problem with him is that he's also an elite slugger, so he's overvalued.

His high OBP is due to the fact that he's considered a "good bad-ball hitter" so he fouls off a lot pitches that other hitters would strike out on, and puts a lot of bad pitches in play that other hitters would miss or foul off. Despite his success, he's still the least-disciplined hitter in the majors, and there's really no disputing those statistics. Even in his possibly-Hall-of-Fame career, he'll still finish with an O-swing percentage around 40%, which is extremely high, and by Moneyball standards, makes the player undesireable. Tejada's O-swing % in 2002 (the year when Lewis was writing Moneyball) was 38%, among the top five in the majors; Eric Chavez was at 34%. Both of them were constant targets of criticism from Beane for their unwillingness to take pitches or draw walks.
Nobody's suggesting that Guerrero isn't a great hitter, but he's certainly not a disciplined hitter. Again, the culture among Dominican ballplayers is that they have to "hit their way off the island." If you want to get the attention of international scouts, you're not going to do it by taking a lot of walks; you're going to do it by crushing the ball out of the park. Hence, the cultural influences that lead to poor plate discipline.
Edit: Here's a list of players with the worst O-swing rates in 2010, and it's clear that there are a lot of Latin players near the top of the list, especially players from the Dominican Republic:

Jackie Robinson's college statistics weren't very good, for a variety of reasons; according to wikipedia, Robinson only hit .097 during his first year at UCLA. If that were the main factor being considered (and for a lot of GMs, it's the biggest one) then yes, he probably wouldn't have been drafed by the Jays. Not because of his race, but because his stats weren't what Moneyballers like Billy Beane and J.P. Ricciardi were looking for. It was a stupid article about a sensitive topic, and it basically killed the Jays' season - but it's hard to get upset at someone for correctly displaying the statistical facts.
Also, I find it hard to get mad at Griffin for hating on Ricciardi - IMHO, he was one of the worst GMs our team has ever had (though Gord Ash is a definite contender for that title). Ricciardi's piss-poor draft record, crappy free-agent signings, and the Vernon Wells albatross contract certainly support that position, and I don't know anyone who thinks Ricciardi did a good job running our team.
