Don't Be a Tool

I am in a nfl.com fantasy playoff league and was wondering if you thought i should take the jets defense again or the san diego defense. the jets defense would get 2x points because i used them last week, but do you think that i should still use them? the team that wins the game gets a bonus 5 points so do you think it is worth taking the jets again or should i take the chargers and hope they advance this week so i can get the 2x next week as well for them?

thanks
