I wasn't really happy with what I did for the offense for this series of posts. So I`m going to redo it. Position by position.
For catcher Jorge Posada has been resigned for the next 4 years. He should be a productive player next year and one of the best in baseball but he`ll drop off. The general opinion around baseball is that he`s really an above average catcher but has never had a season like last year. He posted a .338/.426/.543/.337 line (BA/OBP/SLG%/EQA) with a WARP3 of 10.0. The truth is that 2007 arguably wasn't even his best season. In 2000 he had a 10.4 WARP3 and in 2003 he had a 10.1 WARP3. Not only that but in just 2006 he had a 9.1 WARP3. While 2007 was a fantastic season its not the first time he`s ever had one like that. He also started his career as an infielder so has less years as a catcher in his career and less wear and tear than the average catcher at his age. Jose Molina will also be the backup catcher the whole year and we won't have to worry about having automatic out, Wil Nieves, playing when Posada gets days off. So he should be a little better rested this year. His former mentor, Joe Girardi, is also back with the team and who knows what type of influence that could have on him. He`ll decline but nothing catastrophic. At least not in the first year. Keep in mind this projection is just a ballpark figure made knowing generally how WARP3 is scaled but without knowing the actual formula for WARP3 or using an actual projection system.
2007 WARP 3- 10.0
Projected 2008 WARP3- 7.0
Win Change- -3.0
