The Current NL Central Lineups
I'm using the MLB depth charts, the Bill James projections for wOBA on Fangraphs and their 2012 playing age along with a few assumptions like Dusty isn't going to play Devin Mesoraco or Chris Heisey over veterans. Let's see how the NL Central offenses stack up. Obviously the actual order of lineups and players may vary, and there's no accounting for expected playing time due to injuries or sucktitude.
Furcal(.324), Beltran(.367), Holliday(.394), Berkman(.380), Freese(.353), Molina(.320), Jay(.328), Schumaker(.309)
Average wOBA: .347
Morgan(.311), Weeks(.348), Braun(.411), Hart(.355), Ramirez(.362), Gamel(.357), Lucroy(.319), A. Gonzalez(.285)
Average wOBA: .344
Stubbs(.331), Phillips(.332), Votto(.408), Rolen(.334), Bruce(.363), Ludwick(.323), Hanigan(.324), Cozart (.315)
Average wOBA: .341
DeJesus(.324), Castro(.346), LaHair(.352), Soriano(.331), Stewart(.329), Soto(.344), Byrd(.319), Barney (.294)
Average wOBA: .330
Presley(.345), Tabata(.328), Walker(.329), McCutchen(.360), Alvarez(.333), G. Jones(.338), Barajas(.288), Barmes(.300)
Average wOBA: .328
Lowrie(.341), Altuve(.321), Martinez(.353), C. Lee(.339), Bogusevic(.325), Paredes(.292), Schafer(.288), J. Castro (.287)
Average wOBA: .318
The Cardinals are of course going to have to stay healthy to keep up the offense and that's no small task with Carlos Beltran, Lance Berkman, Matt Holliday and Rafael Furcal on the roster. I'm sure the Cubs are hoping to get a little bit more from David DeJesus and Ian Stewart than their current projections, but doesn't mean it will happen. If and when the Cubs replace Byrd and LaHair with Anthony Rizzo(.318) and Brett Jackson(.342), their average age would go down to 27.125, as would the projected wOBA, albeit slightly to .329 (Rizzo gets no love in the Bill James projections for whatever reason). Another fun exercise for the Cubs is to replace LaHair, DeJesus and Stewart with Prince Fielder, Beltran and Aramis Ramirez because why the hell not? this is all just for fun. In that case, the average wOBA goes up to .345 while also likely hurting the Brewers and Cardinals a bit. Of course, that also has the potential to bring the average DOTDL up to potentially astronomical levels (Dollars on The Disabled List) along with the problem of justifying the $50M or so to pay them for just this year.
I'll see if I can do something similar with the projected pitching staffs in the very near future.
