http://www.fangraphs.com/blogs/index.php/2009-mlb-trade-value-40-36 Fangraphs had Buchholz listed as #38 on their list of Top 50 Trade Values. If we were just talking 2H09 & 2010, Hardy is probably worth more and would certainly be an upgrade for Boston, but as pointed out Buchholz could be a front end of a rotation guy for a number of years. He could be a bust too, but with only a year and a half of control left on JJ's contract he's worth more than JJ. I agree with 804's analysis on wins per year added between the two, my only quibble would be - if Buchholz is worth 2 wins per year, aren't the wins in year 6 worth less today than a win in 2010? Rather than a simple arithmetic adding of wins, wouldn't you use a discounted value? Think of it as a discounted win value, much like a discounted cashflow analysis. The argument against would be he has the potential to be well north of a 2 win pitcher over the next 6 years so maybe you discount 4 wins in half to get to 2. Just curious how you would look at it. I do think we probably have to move JJ in the offseason. Another reason to hope he has a big second half.
