There's no such thing as a trap game. Trap game is a false correlation that players use to describe the reason for a loss, despite that they often exhibit the same loose or overconfident behavior in games where they win. The idea of a trap game also makes the false assumption that NFL players share a collective consciousness.
Statisticians and oddsmakers do not adjust point spreads based on whether or not they think there will be a
"trap game" because the variation of statistics accounts for favorites losing to underdogs. If you go back and look at some of the "trap games" the Patriots have lost over the years, you'll note that their winning percentage against bad opponents is about as expected, or even better than expected, but the fact that no team can win 100% of the time makes us point to specific losses and falsely explain them as "trap games."
Turnovers and other key correlations like red zone offense and red zone defense often explain unlikely losses much better than "attitude" or "preparation", which is a constant in New England and if often a constant for all teams.
