Good comparison of two between Yahoo! Sports' Scott Pianowski and Andy Behrens.
I'm in the Jeter camp - I don't think 34 is that old, and I expect positive regression to the mean for Jeter after an off year, especially in light of his strong second half. Drew, who knows? Could hit 30 homers this year, or could disappoint. Jeter's floor is higher, and their ceiling is equal given that Jeter could hit .315 steal 15-20 bags again.
