MOMENTUM MATTERS
The idea that a team's performance in September has a carryover effect in October is dying fast. Research by SI.com's Jay Jaffe has shown that there is no positive correlation between how a team closes the regular season and how it performs in the postseason. Recent history is littered with teams that stumbled through September—the 2006 Tigers and Cardinals, the '00 Yankees—before racing through October. In the modern game the playoffs are a completely new season with little relationship to the 162 games that came before them. Sorry, Orioles: When the first pitch flies on Oct. 5, forget everything that happened before that moment.
