Because Helton's OPS has decreased by 100 points each of the last two years, going from uber-elite to really really good. However, his OPS is still going to be about 150 points higher than Lowell. Thats about the difference between Izturis and Tejada. If the cubs ended up adding Tejada and subtracting Izturis, what do you think the appropriate reaction would be. Actual differences in OPS between Izturis and Tejada from 2001 through 2006: 2001 - .135 2002 - .306 2003 - .211 2004 - .183 2005 - .240 2006 - .264 Only once since they broke into the league has Izturis been within 150 points of OPS to Tejada, and that was in a season where Izturis only had 140 PA. As much as I would love to think Izturis could pull within 150 points of OPS to Tejada, the only way he does that is if he puts up better than normal-numbers before getting badly injured and limiting his playing time (which I would like as well)... while hoping Tejada has a down year. (Sorry, couldn't pass up an opportunity to stress again how utterly inept Izturis is with the bat.) The past is all well and good, but I'm talking about moving forward. I looked at my PECOTA download updated 1/14. PECOTA projected the difference at 156, although since that has increased to 183.. Other projection systems I did not take into consideration. Bill James (209), CHONE (162), I'm ignoring Marcel because its crap, ZiPS (194). As far as Helton vs. Lowell...Bill James (185), CHONE (108), ZiPS (142). PECOTA at the time of my download was at 123, now at 76 (woah, thats a huge difference mostly attributable to a downgrade of Helton). All projections say Tejada/Izturis is a greater difference, but they vary by degree. James by 26, CHONE by 54, ZiPS by 52, the PECOTA I based the claim off of by 33, and now by 107 (lets average those to 70). So, lets say that my comparison of Tejada/Izturis to Helton/Lowell was overblown by about 50 OPS. Sounds fair to me.
