The best teams generally have the best pitching. There is really no way around it. Team ERA Leaders (1-10): 1 Tampa Bay (90-72) 2 LA Dodgers (86-76) 3 Washington (98-64) 4 Cincinnati (97-65) 5 Atlanta (94-68) 6 Oakland (94-68) 7 San Francisco (94-68) 8 St. Louis (88-74) 9 Detroit (88-74) 10 Seattle (75-87) Seattle is the only team that isn't good and they are 10th anyway. The Yankees (12th), Baltimore (14th), Texas (16th), and Angels (18th) are all good teams, but they at least have average pitching. I think an argument can be made that pitching is a lot more important to team success in the NL than the AL. Nearly every team in the postseason has a great staff and because of this the illusion becomes that the 'best' one will win every year. My opinion is that you have to be very lucky or have a good 1-3 to reach the WS (not necessarily the best). Both teams this season have excellent pitchers and that's a good example and support for this.
