Eh, I'd give the edge to DeRosa. He's had an OPS+ over 100 the last 3 seasons. Going on 4 this year. Can't say the same for Teahen. Though going forward because of his age, Teahen is more valuable. They're both excellent utility players, though.
Anyways, this really sticks it to the Cubs and Hendry. I hope DeRosa puts the Cards over the top, the Cubs don't win the division, and Hendry gets fired as a result. I despise Hendry about as much as Gom despises Cashman.
