I find it hard to sit down and watch any game with absolute confidence that my heroic pigskin avatars will prevail. That may sound funny coming from a Patriots fan; in the last five regular seasons, New England has won 63 and lost 17, a .788 winning percentage. Anyone can have a bad day at the office but Tom Brady has had fewer than most. I should worry? But I do. Even before the games I know they should certainly win (a home game against Miami in December) I suffer spectral anxieties about the rare happenstance only the most sophisticated of predictive analytics could account for. I will regularly consider the game turning on a receiver slipping to the turf, turning a certain reception for a first down into a pick six. That happens. All the time…
