The Momentum Myth
The concept of momentum is bandied about during the post-season as a way for the media to explain and analyze the post-season developments and individual post-season series. Momentum is used as a default explanation for why any given team is winning any given series. When announcers cannot explain outcomes any other way, or want to infuse drama into an otherwise one-sided series, they can talk about momentum, shifting momentum, deflating momentum and other clichés.
