2008 vs. 2009 Yankees by Position

I'm pretending yesterday's game didn't happen, and I advise everyone else to do the same. I've been thinking about exactly how much better the 2009 Yankees are compared to the 2008 version, so I thought it'd be instructive to look at the contributions they got out of each position last year and what they've gotten this year as a quick point of comparison. To do this, I just pulled the positional splits from Baseball Reference.com, so this is not done on a player by player basis, rather it's the combined stats of everyone from when they played a specific position. I'm going to show the PAs, AVG, OBP, SLG and batting runs by linear weights for each position. I'm using a park factor divider of 1.015 for 2008 and a park factor divider of 1.03 for 2009. So batting runs are calculated then divided by the park factor divider (half of the estimated park factor) to park-adjust them. There is no position-adjustment here since we're comparin...
