Hot topic: What's wrong with Cards' defense?

Posted by ESPN.com's Mike Sando

Arizona has allowed more points this season than all but four teams: the Lions, Rams, Broncos and Chiefs. Seventeen NFL teams allowed 350 or more points this season, and Arizona was the only one to qualify for the postseason.

I spent part of Monday speaking with Cardinals players about their defense. The plan is to put together an analysis piece for Wednesday, but not without your help.

What's wrong with this defense? Can the issues be fixed for the playoffs? How much did clinching the division title early play into the team's performance on that side of the ball? Does the offense share some responsibility?

Thanks in advance for your contributions. They've added quite a bit of substance to the midweek columns.
