Jacksonville defense struggling mightily this season

What's the trap? Normally, people use that phrase to indicate that a team is overlooking an opponent in favor of the following game. Why would the Saints be looking beyond Jacksonville to Chicago? I don't understand why this would be the case.

I do confess that I posted an update a few days ago that Mitch Trubisky might be ready for the Saints game. I'm guilty of looking ahead!

I'm also just a fan - not a player or coach - so there's that too! Lol
