Greene in 1000 words or less: Above-average D, good pop, strikes out a ton, can't take a walk, good 2007, awful 2008. 1-year and 6.5 mill left in his contract.

Then again, the last two mullet-headed Cardinals that I can remember have actually worked out. There was late 90's fan favorite Gary Gaetti, and of course 2006 World Series hero Jeff Weaver. Greene and Weaver are definitely competing in some kind of contest. I bet in the locker room they both complain about Mr. Hand constantly. LaRussa is going to go ballistic when Greene has a pizza delivered to the dugout.
In all seriousness, there are plenty of reasons to like or dislike this trade. He's coming off an awful year, but if he turns in 2007 numbers for 6.5 mill, that's probably a good deal. He can't take a walk, but he has good power for a SS. He has a pretty bad career Batting Average and strikes out a ton, but he's played his whole career in an extreme pitcher's park and is entering a contract year. It's very hard to evaluate the deal without knowing the 2 players the Cards traded, but ultimately I think the fact that Greene has only one year on his contract makes this a deal that has more upside than downside, and fills a hole in the lineup. It's better than giving Felipe Lopez the multi-year deal he wants.

Khalil Greene probably doesn't make the Cards much better or worse. Jake Peavy gets the Cards in the playoffs.
