BTBS: Improved/Declined Hitters

Over at Beyond The Box Score, a stat head's dream website, Cyril Morong takes a look at those hitters that helped their cause the most and those who took the most away from what they did in 2005. This is just an interesting article to look at based on the fact that you'll always be surprised at some of the names you'll see. Nobody will be stunned to see Justin Morneau's name on the "most improved" list, but how about Scott Hatteberg and Mike Lamb? I'm also sure most people were dissapointed with Bobby Crosby's year, but did anyone expect to see Jason Varitek and Palcido Polonco on this list? Keep this in mind when trying to figure out who's on the rise and who may be on the way out in 2007. Are these guys setting trends or were they just aberrations? Any thoughts?
