There is a tendency among managers to load up on arms in a pitchers park and load up on bats in a hitters park. The reason for this, in my opinion, is a misunderstanding about "building a team that fits the park."
Having said that, and I'm as guilty as anyone, you CAN win this way. I love playing Billyball in a pitchers park (1970s Oakland A's - Billy Martin - Big Arms - Aggressive Base Running) and Moneyball in a hitters park (20xx Oakland A's - Billy Beane - Value Pitching - Aggressive OPS).
However, I think the pricing of
salaries suggests most managers would benefit from doing the opposite. Mark's Pepperdine team is a good example of this ($21 mil spent on pitching:

Further, here's an example of spending $35 mil on pitching in a more homer friendly park:

I think these routes are more in line with maximizing the player pool as it's currently designed. But when you find lots of like minded people running to the same side of the boat (i.e., 10 managers have the top four *SPs on their draft cards), opportunity arises for the guy left standing by himself looking in another direction. That's why so many different strategies can work, even if maybe you aren't as fully efficient as you can possibly be (according to the "ratings").
