Cardinals/Buccaneers/Saints D/ST

If you had your choice of these 3 for week 1 AND the rest of the season, which one are you rolling with. Prior to preseason I think the Cards would have been the choice but they've had some injuries. Buccaneers, as much as I hate to admit it, look like they're going to have a solid D this year. I love me some Saints defense, but Matt Ryan is my starting QB, and I don't know how counter-productive that'll be for the first week.. I'm worried if I drop the Saints D, they'll get snatched up and I'll lose them for the season if they do go off like I hope.

For reference, first week matchups:

Cardinals vs. San Diego
Buccaneers vs. Panthers (might not have Cam)
Saints @ Falcons
