interesting about the talk of GABP and how you can't build a winner in such an extreme HR Ballpark.
2003-2005 park factors
GABP plays neutral(< 5%) other than LH HR +17 and RH HR+16
The most extreme HR park(even moreso than Coors) is US Cellular at LH HR +31 and RH HR +37.
How did the Sox win in 2005? Simple, they matched their staff to their park. They built a ground ball starting pitching staff.
