I was reading Sullivan's column today (I know, bad idea to begin with much of the time) and he noted that the Cubs systems has eclipsed the Sox in terms of perceived talent level and depth. I found this interesting b/c it seems the two franchises have flip-flopped several times over the last 7 or 8 yrs. At the begining of the decade the Cubs system was on the rise with Hill, Choi, Harris, Pie, Harvey, and all the pitchers. Seemingly overnight the Sox eclipsed them by some distance with McCarthy, the CFs, etc. Now the worm has apparently turned again. I know that many of you follow the minor leagues and high-ranked talent far more closely than I. Is it typical for this to happen so quickly? If so, why? Or is it a reflection of the lack of efficient approach in our system? The Sox aswell? The only team I can think of off-hand with a consistently highly rated system over the last several years is the Angels. Anyone else?
