Konerko is the clear best choice for me. His consistency in previous years shows that last year was a fluke. Dont forget that his averages for the years before last were .294, .298, .282, .304. Along with a .290+ average, he's again a lock for 100 rbi with magglio, frank, and carlos lee in front of him, and his usual 25-30 home runs.
If your starting shortstop is iffy, i can see why you'd pick crosby, but konerko will clearly put up the best numbers of the bunch.
