Whether you've already drafted or still have a some time to make your picks, it's time to start thinking about Week 1.

The NFL season kicks off in just three days, with the Bears and Packers opening the season in Chicago Thursday, which means all of our planning is about to turn into action. We're not just building teams anymore, we're setting lineups. For games that matter.

And we're doing so with plenty of questions still swirling around. What will the Chiefs' and Texans' backfields look like following their weekend acquisitions? How should you handle the Cowboys' and Chargers' backfields? And ... can you even use anyone from the Cardinals?

We look into those questions and more as we begin to turn our attention to Week 1. Our experts have their rankings ready, and are answering some of the biggest questions heading into the week. Plus, Heath Cummings looks into the biggest storylines from the preseason to try to separate fact from fiction.

Oh, and we've still got plenty of draft prep help for those of you who still need it.
