Here's a look at the first basemen and some of the indicators used in developing their 2008 projections (these notes can be found in the software as well). In no particular order:

Delgado, Carlos Eroding skill set, but decent second half, slight bounce up
Lee, Derrek 16 HRs in 2H of '07, however Inflated BA in '07
Helton, Todd Power drop leveled off in '07, at 34YO another drop expected
Konerko, Paul Unlucky BHIPx, average understated by 30-40 points.
Sexson, Richie Unlucky BHIPx cost him 50 points in BA, bounceback
Guillen, Carlos His RBI% was inflated last year, consistency is dropping
Berkman, Lance Production down 15% last year, but only 5% in 2nd half
Huff, Aubrey Dropping Discipline/Dominance, decent 2nd half, slight bounce
Pujols, Albert Was the HR% drop from 7.3 to 4.6 all due to bad back?
Pena, Carlos OPS increased by 300 points last year, high risk to repeat
Teixeira, Mark BA inflated by unjust BHIPx, power should increase
Youkilis, Kevin Big second half fader, Only consistent 8 out of 26 weeks!
Gonzalez, Adrian Still only 25YO, only hindrance is his ballpark
Morneau, Justin Starts off strong, but power fades in 2H. BA should rise
LaRoche, Adam EYE (.48) improved in 2nd half, as did his overall numbers
Fielder, Prince Still improving, plate discipline on the rise
Kotchman, Casey Solid contact/gap hitter, only 25 YO, rise in OPS expected
Johnson, Dan Struggled @ home & against RHP in '07, Solid EYE should impr
Howard, Ryan Despite slow start in '07, most productive days (95) in MLB
Garko, Ryan Full season of PT should increase his overall production
Barton, Daric Only 22, still a few years away from a power stroke
Loney, James Don't overreach here, as Loney needs to develop lift in swing
Gordon, Alex Power spike in second half, rushed to MLB w/ only 1 MiLB year
Votto, Joey Excellent EYE,  immediate fantasy impact expected
