Ready for 2009, You can find them here:
These are based on 5 years of data from 2004-2008, weighted 1, .8, .6, .4, .2. The numbers are a combination of Stats ZR, Revised Zone rating, and Totalzone (which is not available for 2008). Instead of regressing these to a league average, the regression is to a run value derived from the Fan's scouting report. The more a player has played, the more his rating is based on his stats. The less he has played, the more it is based on his scouting report.
Adam Everett is still rated the best shortstop at +19, but it's a steep drop from the +31 he had last year. With his bat, +19 probably isn't good enough to make him a starter, and given his decline on the fan scouting report, he may not even be that good.
