The numbers do not support this. Jones OPS last year was .062 points higher than Giles, for nearly half the cost. The OPS+ for Giles was only slightly less than Jones, but it was still less. Granted Jones had a career year, but Giles downward trend is consistent and notable. He is no more likely to reverse the trend than Jones is to repeat his 2006 year. So Giles is far from a 'significant upgrade' over Jones, when his production is likely to equal Jones going forward at twice the price no less. But OPS doesn't tell the whole story. OPS favors high slugging players. Giles OBP is going to be at least .030 points higher, probably much more. That's a very big margin. Also, Giles moving to a new team and into a better hitter's park, could possibly return his numbers closer to his '05 numbers. I'd say the increase in OBP and chance of him returning to his numbers before 2006 is worth the extra cost. I really don't have much input on the Jones/Giles debate, but here's the problem I have with this and have always had with this and have never had explained. in a 700 plate appearance season, the 'very big margin' that you are talking about translates into 21 additional times on base throughout the season (.375 v .345 obps) is 21 times where the guy who gets on base and theoretically has a chance to score really better if he has 10 fewer HRs were scoring is not a theory but reality? I agree that obp gets under billing in OPS, but I don't think its so vastly more important as it has been made out to be. I agree. Sorry, the 30 extra points of OBP is not worth the difference in power, age and salary.
