"rrhunter" has made two salient points:
Why not bring back Casey or do you figure he'll end up in Seattle with his buddy?Why not indeed? I just said in the body of that post that Blake was likely to outperform anyone we had in the slot, and although he's on the wrong side of the aging curve, I stand by the assessment. My guess is that Blake does not want to relive his formative years with a rebuilding squad (one on which he was, in fact, one of the rebuilding blocks, as it were). And there is something to the idea of Blake playing in Seattle, given that Jose Lopez is likely to leave and this would allow Chone Figgins to move back to 2B, where he appears to have been more comfortable. But let's hold onto the thought for a moment.
