Agreed, any way you slice it, 2B for 2006 looks better than going into this year.
Two other observations:
1) It is amazing how Renteria has fallen from two years ago when there were many people ranking him #3 at the position (OK, I will admit it, myself included).
2) Poor Placido Polanco still gets no love. He figures to start full time in Detroit next year. As always, he will be a lock for .300, a good ammout of runs hitting near the top of the order and 10-15 SBs and HRs. I am not arguing that he should be top five, but I would certainly include him among "useful" 2Bs.
