The entire division doesn't play the Astros now, and we have addressed our run differential issue by getting a high OBP leadoff hitter who will hit in front of a .270 hitter and two spots in front of the .300+ BA doubles machine.
This exemplifies why using run differential from season to season is very problematic. Teams change their rosters in the off-season, players get older, rookies and young players break through, and some players fall off in terms of production. And that doesn't even take in account injuries.
I really think we will discover that the Pythag will become less and less useful as we move forward with understanding the game.
