Most of those guys weren't top 15 pitchers in the years you listed. For example, Pedro only pitched 44 innings in 2009 and went 0-2 with a 6+ ERA in the World Series. Guys like John Lackey, Lester, etc. are not "Top 15" guys (plus, you're listing 3-5 guys per season from two teams, no way they're all "Top 15" guys). They're good pitchers. You know, kinda like Phil Hughes has been this season. I keep repeating this point but I'll do it again: "Ace Pitchers" and "Super Stars" do not win the World Series because if that's the team focus, that team will often miss the playoffs entirely. Those players are nice to have but I'll take a roster of 2009 Jason Kubels over one Joe Mauer and a bunch of league average players. That's what gets you to the playoffs. A bunch of pretty good to really good complementary players, not 1-2 superstars and roster chaff. And once you get to the playoffs, all bets are off. The better players tend to win but that's hardly a given.
