San Diego is losing one of their few impact bats and Gonzalez should be a beast at Fenway Park, but how does the trade shape San Diego's farm system, one that was ranked as the 5th worst by FanGraphs before the trade? Here's their top 5 before and after the trade (from FanGraphs):

This is how I had ranked the Red Sox system, before and after:

After trade:

I personally have Simon Castro just slightly ahead of Kelly and still number 1 on San Diego's list. But the point is, San Diego now has a very intriguing mix of prospects who could help in 2012 and beyond. Since they were probably going to lose Gonzalez after 2011 anyway, now was the time to deal him to get the most value.

From a Red Sox perspective, I really like the trade. They did not have to part with major-leaguers Jacoby Ellsbury or Daniel Bard, and they still have their SS of the future in Jose Iglesias (whose glove is outstanding - mix his defense with the Sox's blend of power/speed and they have a very well-rounded team). Rizzo is the easiest to part with of the three, as he would have been blocked by Gonzalez anyway (though I do love his potential). Kelly should be a very good starter in San Diego, but Boston does not have much room for him on the major league roster the next few years, and I really like Ranaudo and Britton. You had to expect they would have to give up their number 1 prospect to land Gonzalez. I really like Fuentes and I think he is a very interesting prospect, but overall, I am very happy with the trade as a Red Sox fan. Add in the fact that now that they will not be bringing back Beltre they will get draft picks for both him and V-Mart, and the system could be replenished very quickly. I think the Sox need to make one more move, preferably Crawford or Werth, to bolster that lineup for a WS run.

What are your thoughts/opinions on the trade and potential future impact?
