"One stupid play, one stupid penalty, onemistake, ends it for all of us."
Bill Belichick famously uttered those words in 2009, ahead of his team's wild-card meeting with the Baltimore Ravens, in the A Football Life documentary that followed the New England Patriots head coach through the season.
That sentence is playoff football in a nutshell, but especially with regard to the divisional-round meeting between the Patriots and the Kansas City Chiefs this Saturday at Gillette Stadium.
