I never said the content wasn't worthwhile, I'm just pointing out some flaws in it. Constructive criticism should be welcome for any business. Certainly, if you were making women's shoes wouldn't you like to be told that they were causing blisters?
The biggest flaw, since you asked, is the premise that once a player displays a skill he owns it. This, I disagree with. Much like a golfer can come out of nowhere and win the Masters and never win a major again, a baseball player can come out of nowhere and have a great year and never again reach those numbers. And in that great year his BPI's will naturally rise, and if you assume that he has now mastered something new may not neccessarily be the case. Take Luis Gonzalez, for example. In '01 his PX levels were 202, and he had never before even came close to that figure and hasn't since. To project him at those same levels for the following seasons would have been foolish. And they're doing this very thing with David Ortiz. Could he do it again in '04? It's possible, but the chances of him slipping back to his norms are much greater than him duplicating his success. My informal research shows me that hitters who achieve a $5 increase in value over their norms one season have a 67% chance of losing that $5 or more in value the following season.
Conversely, you have Abreu, who's PX stumbled to 110 last season from norms that were closer to 150. HQ jumps on this and assumes he will not return to prior power norms. I disagree with this as well. I believe that when a player slips in any category for one season it's more likely to be a normal fluctuation in a player's career than the beginning of a trend. Maybe these signs are more important when a player ages, but for most players that are close to the prime of their careers I believe this is the case. I learned this at a young age looking at Reggie Jackson's baseball card. His numbers would fluctuate madly from season to season and, if there were such a thing back then, so would his BPI's. I found in my research that a player who loses $5 in value under his norm one season has a 72% chance of gaining the $5 or more back the following season.
In short, I think HQ punishes too harshly for a bad season and awards too lavishly for a good one.
Then there's other cases where they completely ignore trends that are shown in their own numbers. Take Garciaparra. This guys has been slipping in practically every number you can imagine since '99 -- BPI's or traditional stats -- but yet they have him having his best season since '99. It's like they punish more for a bad season than they do for a slow slide. Me, I have Garciaparra slipping into the .280's not only because of this slide (which is obvious not just with the BPI's, but also practically every other traditional indicator) but the fact that by the end of last season he had become a comletely different hitter than he used to be. No more ropes to all reaches of the park but a pull hitter who is too influenced by the Green Monster. And don't even get me going on Sosa.
I could go on further but this is getting long.
I do not think we can compare my projections from prior seasons with HQ's because I never had it on the Excel until these '04 ones. Up until now they've been so scratched and scribbled upon that I cannot decipher most of it. I am more than willing to send my '04 projections to anyone who I feel will be objective in comparing mine to HQ's at the end of the season. I only ask that it be kept sealed from the public until the final results are in because I don't want any, "That idiot had such and such with these numbers." Many of my projections are unorthodox and cannot be judged until the season is over.
And if anyone does accept this I suggest the criteria set in the HQ, which is whose is closer, HQ's or everyone else? In this case, it would be between me and HQ. As Ron will attest, all projections are wrong, it's just a matter of whose is more wrong.
